‡
CDRH Class IIIa is almost identical to Class 3R and 21CFR § 1040.10 (b) (8) describes the hazard as “depending upon the
irradiance, either an acute intrabeam viewing hazard or chronic viewing hazard, and an acute viewing hazard if viewed directly with
optical instruments”.
The following terms are dened as follows:
• Intrabeam ocular exposure: Getting your eye in the way of a laser beam.
• Nominal Ocular Hazard Distance (NOHD): Distance from the output aperture beyond which the beam irradiance
or radiant exposure remains below the appropriate corneal maximum permissible exposure (MPE).
• Accessible Emission Limit (AEL): Maximum accessible emission permitted within a particular class, i.e. the limit
at which one class transitions into another.
• Maximum Permissible Exposure (MPE): Level of laser radiation to which, under normal circumstances, persons
may be exposed without suffering adverse effects.
