1.2 Laser Classification
1.2.1 Laser Classes
Class 2/ll laser products:
Class 2/ll laser products would not cause
permanent damage to the eye under
reasonably
foreseeable conditions of
operation, provided that any exposure can
be terminated by the blink reflex (assumed
to take 0.25 sec). Because classification
assumes the blink reflex, the wavelength of
light must be in the visible range (400 nm to
700 nm). The Maximum Permissible
Exposure (MPE) for visible radiation for 0.25
second is 25 Watt per square meter, which
is equivalent to 1 mW entering an aperture
of 7 mm diameter (the assumed size of the
pupil).
Class 3R/llla laser products:
Class 3R/llla laser products emit radiation
where direct intrabeam viewing is potentially
hazardous, but the risk is lower than for
3B/lllb
lasers. Fewer manufacturing
requirements and control measures for
users apply than for 3B/lllb lasers.
Class 3B/lllb laser components:
Class 3B/lllb components are unsafe for eye
exposure. Usually only ocular protection
would be required. Diffuse reflections are
safe if viewed for less than 10 seconds.
