The word laser is actually an acronym for "amplifying light through stimulated radiation." Simply put, a 1w laser pointer is a beam of light, a beam of photons moving in the same direction. The intensity of any laser depends on the energy it produces, usually in milliwatts. Because these laser pointers come from faraway countries abroad, they are often missed by the safety hazard stickers required by the FDA. If you aim at a person’s eyes at close range, most or all of the light will pass through the pupil. The focused light is further focused by the lens to a strong ("limited diffraction") point on the retina. According to the U.S. Food and Drug Administration (FDA), they have never received reports of eye injuries caused by instantaneous exposure to laser pointers lower than 5 milliwatts.
If you are one of them and want to use 1w high powered laser pointer, but there is not much information about these laser pointers, you can choose 200mW 532nm open-back green laser pointer with bracket key/illumination. This is one of the most popular models of keychain laser pointers and has many advantages. If you don’t know much about this laser pointer model, you can definitely scroll through these laser pointer reviews. He can choose almost any laser pointer according to his needs and budget. If you are one of them and want to use laser pointers, but there is not much information about these laser pointers, you can choose 200mW 532nm open-back green laser pointer with bracket key/illumination.
