he British Conservative Party has been split for a generation over its attitude to the European Union. A majority of Conservative activists advocated leaving the EU, while most of the party’s leading politicians argued that Britain is better off ‘in Europe’.

T

In an attempt to lance this boil, Prime Minister David Cameron forced legislation through the UK parliament to put the issue of EU membership to a referendum. He claimed his own view on whether or not Britain should stay in the EU would depend on the results of his negotiation for reforms. As we now know, this claim was disingenuous. His ‘demands’ were puffed up in advance but, in the end, David Cameron asked EU partners for very little and he settled for even less. In particular, the Prime Minister’s previous pledges to restrict further migration and place limits on the free movement of labour were effectively abandoned. David Cameron then presented his sham negotiation as a diplomatic triumph and recommended Britain vote to remain members of the EU. Even by the standards of UK elections, the referendum campaign was shockingly negative. The Leave side made exaggerated claims over the amount that Britain pays into the EU, quoting a gross figure of £350 million per week which took no account of Britain’s rebate or EU spending in the UK. The Remain side failed to argue any of the benefits of EU membership but instead sought to win solely by frightening voters with escalating horror stories of the dire consequences of leaving; voters were threatened with economic Armageddon, a breakdown in security and even the prospects of a third world war. As readers around the world will know, a majority of the British electorate voted to leave the EU. The votes split 52:48. Despite the narrow margin of the ‘Brexit’ victory, British politicians have shown no appetite for questioning the mandate. The United Kingdom is unlikely to give formal notice of its intention to quit the European Union until later in the year, but there seems little doubt that the country will ultimately follow through on its ‘Brexit’ vote. So far, however, the doom merchants have yet to prove correct. Sterling exchange rates have fallen, but economists now accept that this may give a much‐needed boost to the British economy by making exports more competitive. Economic obituaries predicated on a stock market ‘collapse’ were apparently premature: the big share sell‐off on the day after the referendum had been more than made up within a week. The biggest immediate impact of the UK ‘Brexit’ vote has been the change at the helm. David Cameron was forced to resign. His replacement, Theresa May, has already been installed. A new Prime Minister inevitably means a change of political direction and new faces leading the team negotiating the terms of Britain’s EU exit. For all practical purposes, however, it will be business as usual in Britain and the optics industry. Three years from now, the United Kingdom may no longer be sending members to sit in the European Parliament, but the country will nonetheless continue to trade with the rest of Europe and the wider world.

InternationalSCENE

After t won’t be an amicable divorce’ commented European Union Commission President (and archbureaucrat) Jean-Claude Juncker acidly ‘but then it was not a deep love in the first place’. That observation was made in Brussels (where else?) midmorning on Friday, June 24, 2016. Around six hours earlier, in the cold light of dawn, had come the news no-one in the wide world of politics and business seems to have anticipated. The United Kingdom had taken an unprecedented step. It had voted to leave the EU after 43 years of membership: the first country ever to do so. ‘Independence Day!’ exulted UKIP leader and leave campaigner Nigel Farage. ‘A seismic shock – an earthquake under Europe’ muttered an ashen-faced member of the European Parliament. Over 46 million of the UK's 65 million population were eligible to vote; 72 per cent did so. 48.1 per cent of them voted to ‘Remain’ in Europe, 51.9 per cent voted ‘Leave’ (‘Brexit’). Interviewed in the hours that followed, a high percentage of ‘Brexiteers’ seemed surprised, even embarrassed, by this outcome. One of your columnist's friends, a small business owner-manager, explained. ‘I never seri2

ously thought we’d win’ she said. ‘Basically, it was just a protest vote, against having our views and opinions ignored’. This seemed to have been a widespread reaction. Was this the basis on which a national vote was registered, which will clearly have lasting global repercussions? And how significant was the reported flood of googled post-Brexit inquiries 'what is the EU?' This column is being written within a fortnight or so after the first Brexit dust had settled, with aftershocks still being felt. Politically, in the UK, the first and foreseeable consequence was the resignation of the Tory (Conservative) Prime Minister, David Cameron, who had led the ‘Remain In’ campaign. His replacement, elected by Tory Party members from a short list, will be in post by mid-September. We have been told there will be no General Election. The new Prime Minister will be expected by Europe to take personal charge of leaving negotiations. These will not begin until he or she formally signals the UK’s intention to leave by invoking a process under Article 50 of the EU’s 2009 Treaty of


InternationalSCENE Lisbon. Only the UK can initiate this step. The permitted negotiating period is two years; any extension must be agreed by all the EU’s remaining 27 members. Negotiations will cover legal and administrative issues only; trade agreements will be handled separately. (The UK is short of skilled trade negotiators; New Zealand, having completed its own EU agreement, has already offered to help.) Informal pre-negotiations are forbidden. One reason seems to be the 27’s dismay at the example Britain is setting. In a number of countries – France, Italy, the Netherlands, Sweden, Denmark, the Czech Republic among them – voices calling for EU exit are growing louder. A tough negotiating stance against Britain is needed to discourage the others, it is implied. Moves have already taken place – albeit very politely – to discourage Scotland from separatist plans vis-à-vis the EU. Unlike in England and Wales (where only London, along with Brighton, Oxford, Cambridge and a few others like your columnist’s home town of Tunbridge Wells, decisively voted 'Remain') almost two thirds of Scots who voted in the EU referendum were ‘Remainers’. Scottish First Minister Nicola Sturgeon argued that her country should now be allowed to leave the UK and stay in the EU, and hotfooted it to Brussels to put her case. The response: a very friendly but firm ‘non’. A suggestion that Northern Ireland should leave the UK received (deservedly?) more cursory treatment, but special measures may be needed to solve the problem of the EU’s new land border created between the Republic and Northern Ireland. Effects on business The post-Brexit manoeuvring and politicking will doubtless continue almost worldwide into the Autumn (only interrupted on the continent of Europe by their sacred summer vacances, which nothing interrupts). For the next two years at least, the UK is still a paying EU member. As to the overriding importance of good ongoing political relationships across Europe, this July's centenary commemorations of the First World War Battle of the Somme should serve as a reminder of the peace-preserving motives which helped bring about the EU's formation in the first place. As for the economic consequences of Brexit, they are being felt already. Immediately after the vote, both the value of the

pound sterling and the stock market plunged, with bank stocks especially badly affected. A fortnight later, the markets have staged a fairly strong recovery – but the pound sterling was still well down, to a numbing 84p. against the euro, 1.3 or lower against the US dollar. Transport and fuel costs were hit, along with import costs, impacting on retail sales above all. All three credit ratings agencies – Moody's, Standard and Poor, Fitch – have downgraded the UK, S & P removing our last remaining Triple AAA. There are indications that the UK and the Eurozone may each suffer a ‘shallow’ recession. Fortunately, today’s business context may mean borrowing costs will not rise as they might otherwise have done. The Bank of England has freed up an extra £150 billion to ease the situation of firms and individuals seeking credit. Major international firms are said to be ‘reviewing’ plans to maintain hubs and headquarters in London and elsewhere in the UK. Access to EU market Crucial here will be the question of UK access to the EU’s single market, with its 500 million consumers (after the UK leaves). Brussels has repeatedly stressed that to gain good access, Britain must agree to the EU’s cherished ‘four freedoms’: freedom of movement for capital, services, goods ... and people (= immigration). ‘This last item was Brexiteers’ core demand. Can any negotiation square this circle? Close observers of the post-Brexit scene claim to have detected chinks of flexibility on the part of some EU spokesmen, along with creative thinking like Wolfgang Schäuble of Germany’s suggestion that the UK be given ‘Associate Member’ status. The aftershocks continue to echo through business worldwide, reportedly even dominating the agenda of a recent North American Free Trade Association meeting. It is also reported that the Federal Reserve will now not raise the US base rate this side of the Presidential election in November. Meantime, a further UK interest rate cut from 0.5 per cent to 0.25 per cent is likely, and the Chancellor of the Exchequer has said he will cut corporation tax to 15 per cent in the hope of tempting international business to stay in the UK. As we go to press, Mrs Theresa May, former Home Secretary, begins office as UK Prime Minister, the second woman to do so. W

Zeiss on course to further growth The Zeiss Group has ended the first six months of fiscal year 2015/16 (ended March 31) with an increase in revenue which rose by 5 per cent over the previous year to €2.322 billion (first half of 2014/15: €2.206 billion). At €280 million, earnings before interest and taxes (EBIT) were almost 90 million above the previous year's figure (€191 million). ‘The first half of the year went well overall. We achieved particularly strong growth in the Medical Technology and Research & Quality Technology segments,’ said Dr. Michael Kaschke, president and CEO of Carl Zeiss AG. ‘In addition, the programs initiated to increase the company’s competitiveness are bearing fruit. We will continue with these initiatives in order to maintain and expand the leading position that we already hold in many areas.’ The Research & Quality Technology segment, which includes the Industrial Metrology and Microscopy business groups, reported overall growth, while Microscopy remains at the same level as last year and has not yet met its revenue target.

Dr. Michael Kaschke

Industrial Metrology clearly benefited from the increased demand in virtually all product segments. Medical Technology once again succeeded in expanding its position in the dynamic healthcare market at a high level. The Vision Care / Consumer Optics segment is reporting a strong boost in revenue thanks in particular to product launches in the fields of branded lenses and camera lenses. Zeiss generates just under 90 per cent of its business outside Germany. With revenue totaling €548 million, Zeiss was particularly successful in the Asia/Pacific region in the first six months of fiscal year 2015/16. This corresponds to an increase of 16 per cent over the previous year (€460 million) after currency adjustments. On March 31, 2016 Zeiss had a global workforce of 25,310 people, approximately the same level as the previous year.

‘Brave new world’ beckons contact lens industry Statistics from the British Contact Lens Association conference held in Birmingham, from June 12-13, revealed that just seven per cent of the UK population currently wear contact lenses. Globally, 120 million people wear lenses, representing just two per cent of the world’s population. During a keynote speech at the two-day event at The Belfry, Phil Morgan said advances in technology represented the dawn of a ‘brave new world’ which could trigger a ‘colossal’ change in the way lenses were used. ‘The next 20 years’, he said, ‘will see a huge shift in the way lenses are worn. Rather than being seen purely as a vision correctness tool they will become a lifestyle choice’. The two-day conference and exhibition saw more than 200 delegates get together to share the latest knowledge around contact lenses, with a focus on patient retention and embracing new technology.

The Lenses that change Are photochromic lenses a good idea and worth the money? asks Consultant Editor Richard Chaffin n the 1960’s a researcher at a laboratory of Corning Glass Works in Corning, New York found that a glass matrix with silver halide crystals would change colour when exposed to ultraviolet light. The glass, in the absence of UV light, returned to a clear state. It seems the UV light energised an electron in the silver halide crystals causing them to turn dark. The movement or excitement of the electron always works, never wears-out and is infallible. Corning were not quite sure what to do with this phenomena. It required some further work to produce Photogray and Photobrown glass and then Photogray Extra and Photobrown Extra. These glasses were a remarkable accomplishment and a revolutionary new idea for ophthalmic lenses.

Plastic/organic photochromic lenses

Plastic/organic photochromic lenses did not exist. Nobody was thinking about it or had any idea on how to produce them. There were lots of organic materials that were photochromic but none that oph10

www.optical-world.co.uk

thalmic lenses could be made from. That situation had to change as glass photochromic lenses were beginning to be accepted by the market. However, the process to produce a plastic/organic photochromic lens is entirely different than in glass. After some time, in the early 1990’s, researchers in the chemical laboratories of PPG (Pittsburg Plate Glass) and other companies were able to work out a variety of methods. The process was difficult. For some period of time plastic lenses could not compete or compare to a glass photochromic. In addition, the chemical companies involved were not lens casters. PPG had a process but needed a lens-casting partner to produce the lenses. Essilor, seeing the opportunity for plastic photochromic lenses, was happy to be a 49 per cent partner with PPG. Together, they built a plant in Florida to turn lenses photochromic. The process was one of taking a fully cast lens and imbibing or impregnating the surface of the lens under heat and pressure to make it photochromic.


For PPG this was an entirely different business model than simply selling monomer or chemicals to the lens casters. To be successful and grow the plastic photochromic business PPG offered the process to other lens casters besides their partner Essilor. The business model required cast lenses be sent to PPG for photochromic treatment and then returned to the lens caster for sale. Other companies such as Rodenstock, using somewhat different methods, created their own photochromic lenses. In another development, Corning Glass, seeing the growth of plastic lenses, felt the necessity to have a plastic photocromic material of its own to go along with its glass. Corning’s research laboratory in Fontainebleau, France found their own way to make photochromic lenses. Corning’s entry to the market with a plastic photochromic created more competition but Corning, like PPG, is not a lens caster and needed to sell its material to the lens manufacturers. Since photochromic lenses first evolved three decades ago there have been major advances. The range of movement, the speed of change, the temperature dependency, and life expectancy have all improved. They darken and clear in short intervals of time. Plastic lenses do not generally fatigue in the life of the prescription.

Photochromic lenses today

There are many choices in today’s photochromic lenses. They are available in all the lens materials: glass, CR-39, polycarbonate, and high index. Most, if not all the lens manufacturers sell a photochromic lens. Essilor, with its major share of the plastic lens market, bought PPG’s share of their joint venture Transitions Optical Company. Transitions was the major promoter of photochromic lenses. They advertised extensively, direct to the public promoting plastic photochromic lenses. Their imbibing process treated a major segment of the lens manufacturers, including Sola (Zeiss) and Hoya. Sola and Hoya were major customers of Transitions. That situation has now changed with Essilor a 100 per cent owner of Transitions. Zeiss and Hoya are now going their own way with photochromic lenses. Essilor’s two major lens competitors each have their own photochromic brands either independently or with the help of Mitsui the Japanese chemical company. Mitsui took over Corning’s photochromic Sunsensor technology. Zeiss has its own photochromic lens, Photofusion. Hoya also has its own photochromic lens, Sensity.

Each one of these lenses uses its own proprietary method, either in the lab or at the factory to make their cast lenses photochromic. The photochromic playing field has become more level. A greater number and variety of photochromic lenses are now available on the market.

Are they worth the money?

There are pluses and minuses to lenses that are able to go back and forth between clear and dark. Photchromic lenses do satisfy some people. In their seventh generation going from clear to sunglass in one pair of glasses is the ultimate achievement in photochromic lenses. However, not everybody is happy with these lenses. UV energy may come from other than sunlight. In that case, photochromic lenses might darken when they should otherwise be clear. Photochromic lenses are still temperature sensitive. Hot and cold weather affect their colour and time of reaction. Reaction time, although fast, is not instantaneous. It takes approximately 30 seconds for the lenses to darken and may be as much as five minutes to clear. Photochromic lenses cost more than clear lenses. The additional cost varies according to the type of lenses, single vision, high index, or progressive. They may add as much as 30 per cent to the cost of the lenses. Does that mean that one pair of photochromic glasses are less costly than having two pair of glasses, one as sunglasses? There is really no need for sunglasses to be photochromic. Sunglasses serve different purposes. Many people consider sunglasses to only be a fashion accessory. However, sunglasses also have a very specific function to provide comfortable vision by cutting off excess and harmful light at both the UV and IR ends of the spectrum. Photochromic lenses do not serve as an exact substitute for sunglasses.

Conclusion

Are photochromic lenses then a good idea? The answer definitely is yes. Are they worth the money? To many people the answer is yes. Will photochromic lenses grow in market share? The answer is probably only a little. All lenses will not become photochromic. The human eye has its own way to adjust to different light conditions. Photochromatic lens technology now has given the optical world the same ability.

Smoothing and polishing machinery Tony Jarratt, Technical Editor The title of this article is not really the correct one when we come to look at the actual contents. Over the years, previous surveys have been split into two distinct sections, generating equipment and smoothing (fining) / polishing, with the second part covering two processes, smoothing out the irregularities produced in the generation of the surface and then the final polishing process. Now it will be seen that most manufacturers have been able to virtually dispense with the fining process, by being able to generate a surface that is fine and accurate enough to pass straight to the final polishing phase.

his has profound implications for both the way in which laboratories produce finished uncuts and for the need to stock large ranges of solid laps. This latest change in the production cycle, the move towards ‘ready-to-polish’, has been made possible by the introduction of machines which are capable producing surfaces with an extremely fine finish. This means that they are ready to polish, without having to go through the normal one or two step fining process. To produce such surfaces requires the combination of an extremely accurate machine and the latest types of tool – disc and ball cutters. The level of today’s CNC automated machines and their ever more sophisticated control software, using advanced algorithms has also enabled the most accurate control to be introduced. This software has also allowed the introduction of multi-axis control – a must-have for the production of free-form surfaces. No longer is control restricted to movements in the x and y axes – the latest machines can place the tool at any desired point in three dimensional space, often using five ‘axes’. Using high-speed direct drive shafts, which eliminate inaccuracies in tool positioning and speed variations, the machines can be controlled to extremely fine limits. This means that the surface will not show the usual irregularities produced by ‘standard’ generators. In the past, the use of such machines with single point cutters would have produced a ‘spiral’ profile on the lens surface. This is caused as the ‘point of contact’ of the tool traverses outwards across the lens surface — in a similar manner to the stylus on a vinyl record. Using the edge of a disc or a ball shape to cut towards the centre of the lens eliminates the production of these ‘spirals’, producing an extremely

12

smooth surface. The resultant surface can be passed directly to the polishing station. This latest ‘innovation’ has some profound implications for the surfacing laboratory. First, they will only require one ‘finishing’ line, made up of just polishing machines. The need for fining/smoothing machines will have been removed and thus the total cost of the installation will be lower than it might have been. Second, with the removal of one step in the production cycle, throughput times will be reduced. Although the time to polish the lens surface will be greater than it would have been in a two-step process, this is more than compensated for by the removal of the need to smooth. The overall time will be lower than that of the two processes combined. To enable this change in production manufacturers have made use of innovative processes impossible in the pre-computer age. These include automatic CNC machines, some with robotic handling, which are now widely available and the latest innovations take the ‘art’ even further. As will be seen from the following review, several companies now offer ‘conformable lap technology’. This uses a ‘flexible’ lap, rather than the standard aluminium alloy or hard resin types. The ‘tool’ is made from a thermoplastic material with dual characteristics – it is rigid when cool and softens as it is heated. This means that the tool can conform to the shape of the lens being processed – the final curve being determined by the generated curve, rather than the lap tool – i.e. the old problem of tool curve ‘increments’ is eliminated. Laboratories can work with very few laps to cover all normal requirements (about 95 to 98 per cent of all prescriptions), rather than the normal stock of several hundred. This also


means that the laps can be stored at the smoothing/polishing station, rather than in a tool bank – thus greatly reducing the time required to ‘pick-out’ the tool. Movement of the laps around the workshop is also eliminated. Another innovation, which uses the conformable lap, is that of producing ‘free-form’ surfaces. Without the facility of using these ‘variable’ laps, the ‘individual’ surface accurately produced by the generator would be ‘altered’ if the lens was fined and polished on a standard ‘hard’ lap. Even when a special lap is cut, the chance of the surface remaining true to

the calculated ideal would be small. The conformable principle changes all that. Finally, many systems now generate lenses ‘ready-to-polish’ and these then demand a highly accurate and sophisticated polishing machine, capable of maintaining the correct surface form. Things have come a long way from the days of banks of separate spherical and toric smoothing machines, followed by another bank of polishing machines. Now one polishing machine can accomplish what a number of machines could just a few years ago.

Satisloh www.satisloh.com Satisloh offer a large range of polishers able to handle all lens materials and formats. These robust machines deliver excellent and uniform results, stable and short process times with reduced labour and consumables costs. Diamond turning generating prepared the way for flexible tool polishing. This advanced polishing technology saves considerable costs by eliminating all activities associated with handling and storing hard lap tools. In addition, flexible tool polishing opens a huge window of opportunity for versatility and automation. The Satisloh Flex polishers can process all surface geometries and all organic lens materials. Their polishing processes use the same tangential kinematic technology, while different tools are optimised for individual machine and application types. The various long-lasting flexible polishing tools assure highest form accuracy of the final lens, whether used on a manual or on an automated Satisloh polisher. Combination of motor driven tool spindles and tangential polishing kinematics results in reliable and accurate technology. The processes/machines available are tabulated below. The Toro Flex is a robust dual spindle soft tool polishing system, which offers easy operation, using seven types of flexible polishing tools to cover the full working range of Rx production. It uses the same polishing processes as Satisloh’s automated polishers, achieving the same outstanding form accuracy and integrated tool storage area with lifetime and tool selection. It can produce up to 50 lenses per hour, in the range of 0 to 14D base curve, with cyl to 6D. Lens diameters 48 to 85mm. Micro-Flex is a dual spindle polisher with smallest


footprint and weight, designed for locations that require small floor space and low floor load solutions.

themselves – fully self-sufficient and with the highest level of equipment utilisation. With this, the Modulo Line guarantees easy lab planning and expansion as well as significant cost and time savings. With the CCP Modulo the user gets an extraordinarily powerful two-lens polisher for free-form and Rx lenses. The innovative machine kinematics enable polishing of a very wide range of curvatures. By running all processing in parallel – tool handling and lens handling, lens cleaning and lens polishing – the throughput has been significantly increased compared to leading industrial soft-lap polishers. The new process technology allows for a perfect optimisation of the materialspecific parameters and tools resulting in significant savings in costs per lens. The intelligent interface and conveyor concept of the CCP Modulo enables plugand-play integration into the Modulo Line environment at any stage of lab expansion – from new production start-up to any number of additions for a growing digital-surfacing lab. Features include full flexibility, full speed. Tools and lenses are changed at the same time, and each lens is polished while another lens set is being cleaned. This parallelisation of the processes results in the shortest non-productive time of any softlap polisher on the market. Supported by the intelligent APS system, the tool monitoring and superviCCP Nano 2 by Schneider sion feature enables a self-sustaining polishing process that can run non-stop 24 hours, seven days a week. A new generation of adaptive tools, with high-tech pad materials on the proven ‘click-easy’ lock system, enable shorter polishing times, longer tool life and higher flexibility. The tools are stored on two independently controlled tool drums making the automation simple. The complete pad drum of each polisher unit can be removed and reset in one grip enabling a maximum machine uptime. The outstanding APS (Advanced Polishing System) boosts the effectiveness of the soft-lap tools and polishing routines. Using sophisticated database-driven selection routines, optimal material-specific pads and polishing routines are chosen, resulting in unbeaten polishing performance. An intelligent pad identification system avoids operator based tool mismatch. The sys20

www.optical-world.co.uk

tem monitors the pad wear and sorts out worn pads based on special decision algorithms. So, the CCP Modulo strictly meets the labs quality requirements. Another machine, the computer-controlled polisher CCP 103, represents Schneider’s commitment to the pursuit of perfection. This machine was designed through the consistent refinement of the industryleading polisher, CCP 102. The benchmark polisher CCP 103 offers a significantly larger number of polished free-form and Rx lenses compared to existing market solutions without compromising on quality. A jump to a previously unreachable productivity level has been achieved through the reduction and parallelisation of auxiliary process steps. The result: A fully automated two-lens polisher that starts polishing virtually immediately after the previous polishing job is finished. A special three-channel controller and multiaxis kinematics enable individual processing of lenses. The key element for the high-quality polishing process is the Schneider polishing technology. This allows for efficient processing of the most sophisticated surface geometries and strongest curvatures without form deviations. Multi-step polishing cycles and modern macro technology guarantee the consistent polishing of different plastic materials and all geometries. The new machine features of the polisher CCP 103 are bundled in the performance boosting package. This solution manages several auxiliary steps in parallel: the supply of the next tools, on-the-fly exchange of two prepared tools, and the cleaning of the lenses, respectively. And all this occurs while the polishing process is uninterrupted. The extremely fast tool changer now allows for an efficient exchange between different polishing processes. Optional two-step polishing enables benefits for very sensitive materials and highest cosmetic requirements. The intelligent, fully-automated lens and tool handling system results in a self-sustaining polishing solution running up to 24 hours per day, seven days a week. A new generation of adaptive tools, with high-tech pad materials on the proven ‘click-easy’ lock system, enable shorter polishing times, longer tool life-time and higher flexibility. The tools are stored on two independently controlled tool drums making automation


simple. The computer-controlled tool management system selects the individual tools based on radius of curve and usage cycles. With the adaptive tools, all lenses can now be polished to individually defined prescription curves. The CCP nano is the polishing machine of the extra small and economically priced Schneider Nano Line. The polisher combines best-in-practice technology with smallest footprint at lowest investment costs. Although the most compact free-form polisher in the market, the CCP nano polishes even the most strongly curved lenses up to 18D and delivers premium quality. Smart axis arrangements and Schneider’s unique macro based polishing technology make the CCP nano a machine worth considering. Highest ease of use is gained with the simple to use touch panel that controls the CNC machine with its intelligent processes. The very robust stainless steel working chamber is ergonomic and easy to clean. The CCP nano 2 is a double spindle polisher designed for higher throughput. The polisher combines best-inpractice technology with smallest footprint at lowest investment costs. It is equipped with two tool spindles as well as two workpiece spindles and polishes even the most strongly curved lenses up to 18D with premium quality.

Smart axis arrangements and Schneider’s unique macro based polishing technology make the CCP nano 2 a real winner. Highest ease of use is gained with the simple to use touch panel that controls the CNC machine with its intelligent processes. The robust stainless steel working chamber is ergonomic and easy to clean. Big in performance but small in price – a great choice for start-ups and dedicated lens productions alike. The last machine in the range – the CCP Swift was designed as a fully CNC controlled polisher, specifically for labs to master free-form as well as Rx polishing with ease. The manually loaded machine includes the quality-defining features of the industry-leading automated soft-lap polishers CCP 102/103 like usage of Schneider’s permanent pads, multi-step polishing cycles, and modern macro technology. The intelligent tool management monitors the usage of the pads and indicates to the operator when the replacement of tools is necessary. The transfer of Schneider’s proven and successful polishing technology to the compact class guarantees excellent and consistent results for even the tightest equipment budgets. The CCP Swift is a sound investment in the future for small labs or manually operated larger labs.
