IR optics featuring BBAR coatings Edmund Optics introduces an expanded offering of off-the-shelf infrared (IR) optics featuring broadband antireflective (BBAR) coatings. These include 3-5 µm coating options on Silicon PCX Lenses and Silicon Windows and 8-12 µm coating options on Germanium PCX Lenses and Germanium Windows. Techspec Silicon (Si) Windows and PCX Lenses are manufactured from optical-grade silicon, which is characterised by a low density of 2.329 g/cm3, making it suitable for weight-sensitive applications. Techspec Silicon optics are available with a 3-5 µm BBAR coating in a range of sizes. The lenses and windows feature precision polished surfaces, suitable for a variety of IR applications including IR spectroscopy. Techspec Germanium Windows and PCX Lenses are available with 3-12 and 8-12 µm BBAR coatings and are suitable for use in IR applications that require rugged optics. Germanium is a durable material which is inert to air, water, alkalis and most acids. Techspec Germanium Lenses offer minimal chromatic aberration due to low dispersion. The optics are suitable for a variety of IR applications, including thermal imaging, IR spectroscopy and remote sensing, and are available in a range of sizes. The company offers over 650 stock IR optic designs on a range of substrates, including calcium fluoride (CaF 2), UV fused silica, germanium (Ge), sapphire, silicon (Si), zinc selenide (ZnSe) or zinc sulfide (ZnS). Additionally, Edmund Optics offers quick modifications to stock components to take the user’s project from design to prototype to volume production. Edmund Optics Singapore Pte Ltd

Pipettes HTL has launched the Discovery Pro pipette - a product with low mass and light piston actions. The body of the pipette is carefully engineered to comfortably accommodate those with large or small hand shapes and sizes. The product’s contoured shape eases the required grip strength, and is said to make pipetting motions effortless. The tip ejection force is said to have been reduced by more than 30% due to the push-button-lever system. All internal components are thermally insulated from the handle, eliminating heat transfer from the hand and ensuring accuracy and precision. Equipped with a volume setting/locking mechanism, a 4-digit counter and a soft, thumb-friendly spring system, smooth pipetting is ensured for both 8- and 12-channel pipettes. The pipettes are fully autoclavable, can be user calibrated and come with a shelf- or wall-mountable storage hook. The pipettes are compatible with tips from major manufacturers; Pacific Laboratory Products recommend using Axygen Maximum Recovery and Gentle Fit tips due to their good quality, accuracy and ergonomics. The single-channel pipettes can be purchased individually or in a four pack, which includes 10, 20, 200 and 1000 µL pipettes, a linear rack and tips. Pacific Laboratory Products
