The laser pointers that many people played with when they were young have recently appeared in the "Jianghu" again. I don't know if you paid attention to it. So, does the laser pointer have radiation? Does the laser pointer radiate? Nowadays, with the development of science and technology, a large number of electronic products have entered our lives, including laser pointer. Its colorful light is indeed fascinating. So, does the laser pointer have radiation?
Does the laser pointer emit radiation? There is no radiation when the laser pointer is not in use; there is no ionizing radiation such as X-ray when in use, and it is somewhat similar to ordinary electromagnetic waves like a flashlight when in use. However, it should be used reasonably and correctly to avoid injury.
It is recommended to use them reasonably. Many of the laser pointers and laser flashlights on the market are of class IIIB with a power exceeding 5mW. If the laser is directed into the eyes, it may cause damage to the eyes. For some high-power laser pointers, the diffused light may also cause damage to the eyes, and it is more likely to ignite flammable materials after focusing.
Therefore, the laser pointer is not a toy and is not suitable for children. If you are operating a high-power green laser pointer, you should wear special safety glasses, especially the invisible laser. Also, no matter how powerful the laser is, it must be avoided to hit yourself and other people's eyes, and the laser itself should also be marked with warning labels.
Laser pointers, also known as laser pointers, pointing stars, etc., are pen-shaped transmitters designed to be portable, easy to hold, and processed into laser modules (light-emitting diodes) with visible lasers. Common laser pointers include red light (λ=650~660nm, 635nm), green light (λ=515-520nm, 532nm), blue light (λ=445~450nm) and blue-violet light (λ=405nm).
It is usually used in reporting, teaching, and tour guides to project a light spot or a light directed at an object, but it is not suitable for use in certain places, such as art galleries (some paintings are afraid of light), zoos, etc. Remember! If you are using a laser pointer, you must not directly irradiate your eyes or flammable objects and valuables, safety first!
