How much 2000mw blue laser pointer?

The color of the laser beam is determined by the wavelength of the light emitted by the laser diode into the laser pointer. Our laser pointer only emits green light. Green light is the most visible color to the human eye. This makes the beam of our laser pointer very bright, showing a spectacular vivid green. On the other hand, tricky green laser pointers do not emit green light to each other, they also emit infrared light. Infrared rays are invisible to the human eye, so the light beams emitted by these low-quality LED laser pointers are not as bright as they should be, and they are very dangerous. There is an infrared filter inside the real green laser pointer, which can block infrared rays. Poor quality shotgun tuned lasers have removed this filter. Without this filter, these laser pointers are very dangerous. You may hurt your eyes, and you don't even realize it until the end. The pointers of the indicators are more dangerous than their packaging requirements. In the measurements performed by the Federal Office of Metrology (METAS), 95% of the tested products exceeded the effective limit. One of the pointers is even 1000 times stronger than claimed.
