How to judge the type of laser pointer?
Another use of lasers in cave exploration is to examine underground pools and streams. If the water inside the cave is clear, use a high powered laser pointer to illuminate the underwater terrain so that people on the surface can see it. This method is not as effective as putting bright light into the water, but can be done from a distance without entering or contaminating the water. In most cases, you should only use a low-power blue laser beam in caves, as it can harm cave creatures, especially bats. Bats are easily disturbed by bright lights, and when disturbed during hibernation, they tend to grab hold of the roof and fly away, sometimes leaving the cave. Due to the continuous development of laser technology, high power green laser Pointers are very popular in some special fields. Of all the laser equipment available, the high power 10,000 mW laser pointer is a real surprise for all laser enthusiasts and hobbyists.Unlike traditional lasers, the green laser pointer has about five times the visibility and brightness of the red laser. As a result, this 10,000 mW green laser designator is more than 8,000 times brighter than the sun. I really can't imagine why it's so powerful. Visible light reaches 15,000 to 28,000 meters in the atmosphere. No laser is better and brighter than this powerful 10,000 mW green laser pointer. It's just the brightest laser in the world that you can legally own.

One of the brightest hand-held lasers in the world, this 1000mW green laser pointer looks 8,000 times brighter than looking directly at the sun. Seeing that number for the first time was a real surprise for me. Therefore, laser safety glasses become necessary every time the high-powered laser pointer is used. With a permanent power output of 1mW, you don't have to worry about school education, university lectures, exhibitions, lectures, astronomy. The 1mW Class II blue laser pointer will not cause damage to the human eye or skin. Liang or points. The 635-nm red laser pointer is recommended, and is less visible than the green laser, enough to be formally demonstrated in school education, star positioning and astronomical research. Laser protective glasses are not required. In addition, do not point any type of laser pointer at a moving vehicle, aircraft or aircraft. There's a big, sharp laser beam that temporarily blinds the eye. Whenever people point to a pen-laser device, don't put it in the wrong hands or overuse it.
