How much green laser Pointer SDlaser 303?

One of the easiest ways to determine the legitimacy of any laser pointer business is to simply look at the warranty provided by each model and its support network. Will they respond to emails? Is there a phone call and live chat? If you need help, can you get help? You can clearly see how much confidence they have in their products based on the level of support provided by laser suppliers and the guarantees provided by product quality. At night, due to the Rayleigh scattering of atmospheric molecules, even low-power green light can be seen, and astronomers often use it to guide stars and constellations. The green laser pointer can have multiple output powers. 5mW is the safest way to use it and can be seen in dim light, for which no more power is needed. Blue laser The original only uses the DPSS 473nm blue laser, which is low in power and unstable. With the development of CASIO blue laser diode (445nm) hybrid light projectors, blue semiconductor diodes with a power exceeding 1000mW (fourth) have been mass-produced and promoted. Generally speaking, a low-power laser pointer seems to have a short range, and only 532nm is sufficient, and it will not affect the aircraft. I think 200mW 532nm is the best method.
