Special portable green laser pointer

Another use of lasers in cave exploration is to inspect underground pools and streams. If the water in the cave is relatively clear, a laser pointer can be recommended to illuminate the underwater terrain so that people on the water can see it. This method is not as effective as putting strong light into the water, but it can be performed from a distance without entering or contaminating the water. Compared with traditional astronomical observation tools such as single rods, human fingers, astronomical telescopes, etc., people can get a completely different experience from the special astronomical tool-a green laser pointer with a mini safety lock. In astronomical research, people usually have to point, wave their arms, scream loudly, and point to celestial bodies to explain a lot. The current power range of high-power green laser pointers and portable green lasers is from 5mW to 50,000mW.

The former is often used for simple high power laser pointer beam demonstrations, while the latter is widely used for graphic laser demonstrations. The scanning head is characterized by a maximum deflection angle of 80 degrees. However, compared with other types of optical deflection systems (such as polygon mirrors, acousto-optic deflectors), the scanning frequency is limited due to reentry and acceleration time. With a permanent power output of 1mW, you don't have to worry about school education, university lectures, exhibitions, lectures, and astronomy. The 1mW Class II blue laser pointer will not cause damage to human eyes or skin. You can use the recommended beam of a high-power laser pointer to point the object far enough, pop a black balloon, burn a black match, or cut electrical stripes. This more powerful green laser pointer is no longer a toy, but an entertainment tool, which should be kept out of the reach of children.
