Electrical and Optical Characteristics

(Tth: Thermistor temperature, Tth = 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, uncollimated

laser diode beams are fairly safe at a laser

diode. 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.
