Where is the determination of laser pointer color and range?
The general public often asks what is the range of the laser pointer. In response to this interest, some manufacturers have specified dubious figures.
If the question of how far the laser pointer's light can travel is correct, there is no limit to the correct answer as long as the light is not absorbed or scattered in the atmosphere. However, the spread of the beam eventually increases its area. Even if the total power stays the same, it will decrease on the screen. As a result, the pilot of the aircraft looking down on the beam from an altitude of 10km will not be disturbed by the remaining small intensity. Don't worry too much if you aim the Rechargeable Laser Pointer's recommended beam directly at your eye. A beam of light entering the eye can cause temporary flash blindness and mutilation. It's not hurt. Instead, it's a normal reaction of the eye to overbright light. This is similar to what happens when you look directly at the camera flash. When you look directly at the light, the remnant area looks like a speck, but when you move your eyes during the exposure, it looks like a single point or line.

Laser monitoring devices exist, but they have some disadvantages that make them unsuitable as a measurement solution for evaluating beam stability. For example, some monitoring solutions do not measure beam power at the operating point where the beam interacts with the material. The current monitoring system is not a suitable global solution because a serious failure can occur anywhere in the path of the blue laser designator beam. Laser power measurement has long been a staple in research, medical and manufacturing applications. But now, laser power measuring devices are being incorporated into car manufacturing more than ever before.
