For the wavelength between 400 and 700 nm, the two types of lasers do not allow human exposure beyond the level of 2. Any emission beyond this wavelength range must be below level 1. Laser wavelengths are between 400 and 700 nm, and may be dangerous when observed with optical instruments. Any emission beyond this wavelength range must be below 1M level. The range of Class 3A laser is 302.5 and 106 nm, which has potential danger, but the risk is lower than that of Class 3B green laser indicator. For the wavelength between 400 and 700 nm, the emission limit is less than 5 times of the second stage, and for the wavelength outside the region, it is less than 5 times of the first stage AEL.
