Which color laser pointer is brighter under the same wavelength?

They are also useful in any situation where special items need to be indicated in educational situations. Pointers can be purchased at novelty stores, mail order magazines, office supply stores, general electronics stores, and the Internet. There is a class IIIa laser, which must be less than 5mW (measured light output, no electrical input) according to the law. Such sales are legal in the United States, and operations outside the United States are legal (local or state exceptions may apply), provided that you do not do anything stupid. The wavelength range corresponds to the wavelength of the laser. The beam size refers to the maximum size of the beam when it leaves the green laser pointer. The beam divergence refers to the change of the beam size with the distance from the laser. The important characteristics of the laser geometry to be considered are the length, width, height, and weight of the laser. Common specifications for continuous wave lasers include average power, longitudinal mode spacing, and RMS noise. The laser is determined by the actual wavelength or frequency of the light. Among the visible spectrum light, 532nm green is the brightest laser color to the human eye under the same output. This means that if we look at a 200mw laser pointer, the green will be brighter than another 200mw color. Whenever considering the use of high-power laser pointers, safety must be the top priority. Since some of the more powerful devices generate a lot of heat and are very bright, they must be used with caution and anti-wavelength safety glasses.
