Laser radiation versus “ordinary light”
... Class IIIb Will cause damage if the beam enters the eye directly. This generally applies to lasers powered from 5–500 mW. Lasers in this category can easily cause permanent eye damage from exposures of 1/100th of a second or less depending on the strength of the laser. A diffuse reflection is genera ...
