Safe Use of Green Laser Pointer

5mW green laser pointer belongs to Class IIIa laser with 532nm wavelength, uses two AAA batteries. This type of green laser projects 532nm green laser beam with high brightness, so it is extremely dangerous to eyes, especially high powered lasers. In many countries and regions, only allow 5mW green laser pointer.

Early laser pointer only uses 633nm helium-neon (HeNe) gas laser, typically for generating power of not exceeding 1mW laser beam. The cheapest laser pointer uses near 670nm/650nm dark red laser diode. Slightly more expensive laser pointer uses 635nm red laser diode, with near orange red color laser light. 635nm wavelength is much more easily recognized by human eyes. At the same time, there are other colors of laser pointers, the most common is the wavelength of 532nm green laser pointer.
