Laser pointer-attractive light
The only real safety issue that users need to consider when irradiating laser beams is to pay attention to reflective surfaces, which may repel light into the eyes of the user’s own audience. In addition, do not screw into airplanes or vehicles. This is very dangerous and very illegal. Yes, it turns out that many creatures are attracted by the alluring power of the little pink dot. We are no longer completely sure why—it may be that the movement of the dot shows life, or its brightness suggests an extra delicious snack—maybe like a strange worm. Preferably a laser pointer. Even if the user uses a high-power pointer laser for line generation online, the blue laser can be sent with very high brightness. Whenever users use this powerful laser pointer to generate this line online, they need to clearly understand the target length, width and distance of the red line.

The power output of green high powered laser pointers commonly used by astronomers and the general public is less than 5 milliwatts; in the United States, these are called Class 3a lasers. Low-power lasers, which are equivalent to lasers in CD players and laser printers, belong to category 1 or 2, while high-power gadgets that correspond to these in clinical or industrial equipment belong to category 3b or 4. The color laser pointer emits laser light and has excellent performance in terms of the angular width of the laser beam and the divergence of the beam. It always projects a divergent green laser beam in the dark, which can easily pass through the atmosphere to reach directional celestial bodies.
