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
