Best Laser Color Introduction

          Common laser colors are red, green, blue, purple, yellow, etc., each color also corresponds to a variety of different wavelengths. However, so many colors, in the end which color is the best choice?

          The answer that a green laser is the most visible. There are two important reasons: on the one hand, the eye sees green better (more efficiently) than other colors. on the other hand, in the same power, green laser will appear much brighter than red or blue laser.

          Note that in terms of eye injury hazards, the color does not matter. More milliwatts means a greater potential eye hazard, no matter what the beam color. (This is for visible lasers; for infrared or ultraviolet lasers, the primary injury area is the cornea and not the retina.)
