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 (Tth = Thermistor temperature, Tth = 25°C)

Handling Precautions

Eye protection against laser beams
The optical output of laser diodes ranges from
several mW to 10W. However the optical power
density of the laser beam at the diode chip
reaches 1.5MW/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.
