Wavelength and Optical Density. Laser Safety Glasses are chosen based on your laser’s operating wavelength and strength. Wavelength is measured based on the “spatial period” of a wave—the distance over which the wave’s shape repeats. It is usually measured from a point to the next time it repeats (crest to crest, valley to valley, etc).
