What is the power of an astronomical laser pointer?
Astronomy Burning Laser Pointers is an ideal tool for astronomy professionals and amateurs. The bright beam of laser pointer can quickly and easily point out celestial bodies in the sky. The highly visible laser beam appears to touch celestial bodies such as planets and stars, and your friends and viewers can clearly see these celestial bodies. The color of the laser beam is determined by the wavelength of the light emitted by the laser diode indicated in the laser pointer. Our laser pointer only emits green light. Green light is the most obvious color of the human eye. This makes the beam of our laser pointer very bright, showing a spectacular bright green. On the other hand, the sloppy green laser pointer emits not only green light but also infrared light. Infrared rays can be seen by the human eye, so the beam of this inferior laser pointer is not bright enough and it is also very dangerous.

Laser lens: The laser lens is on the front, and the laser is covered by the front cover. It is always possible that the lens is dirty, and a small amount of dust on the lens will cause the laser beam to be scattered. Laser lenses are more sensitive than camera lenses and can be cleaned by professionals in the photo studio or with professional equipment. Class 3a lasers can emit visible and/or invisible laser beams with a maximum output power of 5 mW. For accidental exposure, due to people's normal aversion to strong light, this type of laser cannot immediately damage the eyes. However, deliberately staring at the laser beam or observing the laser with optical instruments is dangerous and should always be avoided. Many architectural alignment lasers fall into category 3a. Class 3b lasers are medium-power, medium-risk laser equipment that can emit ultraviolet, visible or infrared laser beams. The laser beam of the 3b laser can have an output power of 5 mW to 500 mW, and the emission duration is greater than 0.25 seconds. These lasers can cause temporary and permanent eye damage through direct beam or specularly reflected beam irradiation.
