SLD402S

Optical and Electrical Characteristics

(TC = 25°C)

Handling Precautions

Eye protection against laser beams

The optical output of laser diodes ranges from

several mW to 3W. However the optical power

density of the laser beam at the diode chip

reaches 1MW/cm2. Unlike gas lasers, since 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.

In addition, the laser diode array of this product

is not protected by window glass or other

covering (open package product ), so special

care is necessary when handling.
