Laser Protection Concepts:

MPE [maximum permissible exposure] laser radiation level that will not cause hazardous or adverse effects to exposed individual
NHZ [Nominal Hazard Zone] region where the applicable MPE
is exceeded
NOHD [Nominal Ocular Hazard Distance] distance along the unobstructed beam from the laser to the eye, beyond which the applicable MPE is not exceeded.
MPE depends on wavelength, exposure time, and target organ
[eye or skin];
Higher MPE Lower hazard
