High-power green laser can focus, 1000MW green laser pointer can focus seconds to light newspapers, and can quickly light cigarettes. 10000mW blue laser pointer can effectively disperse birds. The most important thing is that everyone has their own characteristics. We have to look at everyone's preferences. The 532nm green laser pointer casts the brightest green light at night and during the day. Unlike direct diode laser Pointers, 532nm green laser Pointers do not have a 100% laser conversion efficiency. However, when we do not see the laser radiation of 532nm green laser, stealth infrared laser may come out of the laser aperture. Laser users should not look directly at the beam from a 532nm green laser pointer, because infrared laser is very dangerous once it is aimed at the eye. Once the eyeball is exposed to this powerful laser, the invisible 1064nm infrared laser can cause blindness.
In fact, class 3 or 4 green laser pointer can be dangerous when the laser hits or reflects back to the body, especially the eyes. The higher the power, the shorter the exposure time for damage. Avoiding laser beams is like avoiding being burned by fire, it is enough for your safety, if you need to watch the shining laser for a long time, professional laser glasses will be safe for your eyes. Power The power of laser Pointers is measured in mW (milliwatts). Lasers sold in online stores typically range in power from 1 mW to 60,000 mW (depending on the unit). Many green lasers below 200mW May be very bright, but are not necessarily defined as high power lasers. If you're looking for a burning laser, you need 20mW or more (any color), and the more powerful the burn, the more powerful the burn.
