Standards for laser radiation

On the basis of an analysis of experiments on interaction between laser radiation and the eyes of experimental animals, and also taking into account the optical properties of the eye, a method of calculating the maximum permissible exposure to laser radiation for the case of a single (nonchronic) exposure of the eye is proposed and substantiated. Maximum permissible exposures are given for pulse durations of $10^{10}-10^{-1}$ sec in the 0,4-1,4 $\mu m$ spectral range for an arbitrary angle of convergence of the beam, including the case of exposure to a collimated beam, for any level of adaptation of the eye.
