Powerful 3w laser pointer produces a highly visible and distinct beam into the night. Because of its light beam, the interference of strong anti-stray light, and it is increasingly used for teaching / astronomy, construction site, field exploration to From A pleasant and exquisite design, this type of product is very acueilli on the market, it also has a range of 5000mètres - important for a laser of this puissance.vu its high power, you have to be careful when you utilisez.Ce 3000 mW laser pointer has a wavelength of 532 nm which gives a particularly intense green color (against 650 nm for red and 405 nm for blue). Is the wavelength of the most visible to the human eye.3000mW green laser is an extremely powerful laser, with beautiful finishes, closer to the lightsaber that the laser pen!This is ten times brighter than a red laser because of which cheap 3000mw green laser pointer can be seen from miles away. This is due to the fact that the green color is closest to the center of the visible spectrum and thus more easily visible than red.our work, this green laser 3000mW operates with high capacity 18650 batteries a longer operating time.Furthermore, the supplied extension ring can be removed so that the laser operates with 16340 cells smaller, available online.For the beam power is maximized, use batteries or fully charged batteries.

This 20000mw laser pointer has a strong power and has a wavelength of 405 nm that gives the color blue so special. If this wavelength is less visible than that of green lasers, the blue laser is not less powerful. It therefore presents similar risks and involves precautions identical with a 200 mW green laser. To operate, the laser requires the use of a rechargeable battery CR123A.Choice of green laser pointers to good doctors, lecturers and audiovisuelles.Ces green pointers for presentations are made rigorously checked individually to offer you a reliable and durable product.We also offer you pointers IIIb class whose power is higher than 5mW intended for professional use including in astronomy or for laboratory experiments. The high performance lasers are classified IIIb laser. These lasers have arrived recently in the global market, especially in military applications and physics laboratories. These lasers have nothing to do with small lasers bought at the market that are usually less than 5mw while those high performance range from 50mW to 1500mW.
