The green laser pointer is still visible from miles away. Therefore, in the current astronomical observation missions, astronomical researchers and laser enthusiasts hope to choose a bright green laser pointer for demonstration. Conferences, lectures, astronomical observations, exhibitions and presentations. If the user makes appropriate laser beam adjustments in the steering direction, this advanced green laser pointer and slide changer can play an excellent role in any occasion. Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the naked eye, such as ultraviolet or infrared radiation. Generally speaking, laser radiation itself is not harmful and behaves very similar to ordinary light in its interaction with the body. Laser radiation should not be confused with radiation from radio waves, microwaves, ionizing X-rays, or radioactive materials such as radium.
If you choose a very low output power, you will not see the laser pointer and slide changer beam at night or during the day. The beam of the 532nm green laser pointer up to 30mw is clearly visible. During the day, you can even see the green laser beam indoors. A laser pointer with a higher output power will produce a stronger and more intense green laser pointerbeam.
