Do you know how to use the laser pointer correctly?
In the '90s, the laser revolution led to the democratization of the use of the technology, especially the use of green laser pointer in everyday life. Today, there is no denying the success and laser Pointers are becoming more powerful and sophisticated. It can be used for many uses and applications in very different fields, such as education, teaching, advertising, conferences, architecture, astronomy, tourism and scientific research. An outdoor laser show can also be considered part of an amusement park laser show/multimedia show or corporate show. They are also often used for inaugurations or the launching of buildings/building objects. Some light artists also like to use laser show systems in their outdoor installations. The 2M laser has a wavelength between 400 and 700 nanometers, which is potentially dangerous when obtained using optical instruments. All emissions outside this wavelength range must be less than class 1M AEL.

Every 10 mW will be collected and the power measured will exceed the 3R AEL. Products should be placed in category 1M as this is the minimum AEL not exceeding. The irradiance is at least 3 times lower than that of MPE for exposure times of 0.25 seconds and lower than that of MPE for exposures greater than 10 seconds. When measured with a 5 cm opening.

Class IIIb: Class IIIb Laser Products Any laser product that allows human exposure to levels of laser radiation in excess of the permissible contact emission limits set forth in Table III-A during operation, but does not allow human exposure to levels in excess of the listed contact emission limits set forth in Table III-B of 21 CFR Part J 1040.10 during operation. Class IIIb high powered laser radiation is considered as an acute hazard of direct radiation to the skin and eyes. Class IIIb laser products may have removable panels that, when moved, can be exposed to laser radiation levels from Class II to Class IV. Class 3R lasers, between 302.5 nm and 106 nm, are potentially dangerous, but less risky than class 3B lasers. The reachable emission limit is less than 5 times that of class 2 AEL for wavelengths between 400 nm and 700 nm and less than 5 times that of Class 1 AEL for wavelengths outside this region.
