You have to consider not only the different functions, but also all the major laser colors that we have been accustomed to for years. laser pointer app are available in many colors, each of which has a different purpose. The color of the spot or beam of the laser pointer directly corresponds to the wavelength it emits. Although red lasers are most commonly used in homes, blue and green laser pointers are becoming more and more popular.

Therefore, the laser is compatible with Class 1 to 3R. With a laser pointer, the distribution of output values ​​is usually very large, even if it is a 3W laser pointer model with the same structure. This means you will also get a laser pointer with an output power of 10 mW (these laser pointers usually correspond to category 3B) and have no corresponding markings).
