Warranty

This warranty period shall be 90 days after receipt of the
product or 1,000 hours operation time whichever is
shorter.
Sony Quality Assurance Department shall analyze any
product that fails during said warranty period, and if the
analysis results show that the product failed due to
material or manufacturing defects on the part of Sony, the
product shall be replaced free of charge.
Laser diodes naturally have differing lifetimes which
follow a Weibull distribution.
Special warranties are also available.

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.
