Electrical and Optical Characteristics

(Tc: Case temperature, Tc = 25°C)

Handling Precautions

Eye protection against laser beams

The optical output of laser diodes ranges from

several mW to 1W. However the optical power

density of the laser beam at the diode chip

laser diode beams are divergent, uncollinated

laser diode beams are fairly safe at a laser

diode. Generally speaking, however, it is best

NOT to LOCK into laser beams, under any

circumstances. For observing laser beams,

ALWAYS use safety goggles that block infrared

rays. Usage of IR scopes, IR cameras and

fluorescent plates is also recommended for

monitoring laser beams safely.
