Buying Tips for Class 3A Lasers
Power and wavelength
Class 3A laser pointers are medium-to-low power lasers with an output power of 1-5mW. They are generally visible, and the wavelengths are usually 405nm, 450nm, 520nm, 532nm, 635nm, 650nm, etc.
Safety tips
Under normal circumstances, the class 3A laser will not cause damage to the eyes in the blink of an eye. However, if you observe through optical devices such as telescopes or look directly at its beam for a long time, it may cause damage to the eyes.
Application areas
Due to their characteristics, class IIIA lasers are used in many fields, such as laser measurement, laser treatment, medical beauty, laser experiments, and presentations.
