Classification of laser swords
Laser swords are divided into 4 levels according to their output, and the weakest are [Class I, Class II, Class IIIA, Class IIIB. In the past, Class IIIA toys were also sold in the form of keychain toys, but due to the danger, they are not seen anymore. 20000mW laser pointers for meetings and presentations are available from stationery manufacturers, etc., but they are all Class II high power laser pointer. Since it can capture the receiver signal within a radius of up to 30m, even if you operate the slide at a certain distance from the PC, you can move the slide without any problems. The laser pointer cat’s eye can be used continuously for up to 4 hours, and it will only light up when the light button is pressed, so it can be used for a longer time.

Laser pointers with a long range often distract or annoy them, or are often maliciously illuminated by people for fun. This is especially dangerous for aircraft operators. MSNBC reported that the FAA recorded more than 2,836 incidents in 2010. The illumination of the handheld green laser is particularly severe because the wavelength (532 nm) is close to the peak sensitivity of dark-adapted eyes. Its brightness is 35 times that of a red laser pointer with the same output. Please take this opportunity to appreciate the magical, highly recognizable green laser. It is a very convenient tool. It uses a very bright green laser pointer and is used in industrial and scientific fields. In addition, it shows a high degree of compliance with safety standards, professionally applicable light sources for medical pain treatment, government monitoring, and high stability in the night vision lighting for military laser pointer cat eyes.
All lasers are focused by a focusing lens, but the divergence angle of solid-state lasers is reduced by semiconductor lasers, so the light energy of green laser pointer is more concentrated. Members of the laser projector community are concerned that irresponsible use of laser pointers may lead to legislation affecting lasers, which are abused in projectors and designed for use in the entertainment industry. Often irritated. Other activities involving glare or distraction hazards are also worthy of attention.
