What Separates the Green Laser Pen From the Rest? Perhaps the green laser pen is the most used beam light in many activities, from various demonstrations to star gazing. One could easily explain any presentation to a wide audience. Constellations and stars could be more visible even on a very dark night. This helpful gadget comes in various models for unique purposes. Firstly, knowledge of these products is crucial in selecting the right one appropriate for your purpose of use. Being familiar with your goals would give you a precise benefit to make the best use of a certain beam light pen. Laser light technology has enabled many items to be manufactured. Your presentation or visual control of astronomical bodies would be enhanced if you get the right one. The green light offers the highest sensitivity to the naked eyes which makes this device appropriate for heightened visibility. It is also an ideal accessory mounted on a telescope to enable better alignment and directed viewing of the heavenly bodies. A secondary task for you before buying is that you perform a little research. You could simply type in the search engine of the specific product you want and see what review sites have to offer. You could find details about the quality, price, special offers and aesthetic value of different merchandise. To help you tell the difference among several types of such item, read on the following details per pointer product. Most of the pointer pens of this color are under the IIIa or EIC Class 3a classification. These are referred to as the 5 mW lasers. However whenever you will get this kind, you would see that it might be lower than the said optical output. This is because the FDA has mandated a limit for pointers that could be used for simple purposes. The others that emit between 5 mW to 500 mW are under the Class IIIb or IEC Class 3b. These ones are strictly and legally mandated to be not promoted as simple pointer pens due their extreme beam light. Also, the beam of over 150 mW lasers could light up matches. Hence, it is of the utmost importance that you carefully scrutinize the product labels and instruction guides. And that you need to be always careful in using any. The below samples of the green lasers are suitable for astronomical gazing and demonstration or in activities like laser light shows that have extremely secured environment. The 10mw Green laser pointer usually has the wavelength of 532 nm. Most brands could be operated by two 1.5 volts AAA Alkaline batteries. You could also see up to 7 miles away during nighttime. The 20mw green laser pen has much alike qualities of the previous sample. However this one allows you to see up to 8 miles, which makes it a powerful tool for military sights and light up the clouds. As for the 300mw green laser pen, the power source usually

requires one 3 volts Lithium batteries. It has laser pen range more than 100 miles. Most brands are equipped with heat sink and cooling technology so extreme activities could have continuous operation. This product could perform from highlighting the stars, scientific experiments to industrial purposes like building and architecture. Laser pen modification may be possible only if you have the appropriate knowledge, self-help methods recommended or crafted by professionals. You should be cautious in doing this task. First of all, when you install the wrong additional accessories, the light emitted would then be hazardous. You must also have safety gear and appropriate equipment like safety goggles, a soldering kit and other tools like screw driver and pliers. This is only suitable for points with 5 mW or less output power. Choosing the green laser pen might be an easy task. But each decision you make should be accompanied by enough research so your needs could be properly answered too. To learn more about Green Laser Pen, please visit
