LASER DIODE
Never look at the laser light beam through the objective lens. T he visible laser beam may harm
the human eye. Use an appropriate viewer or TV camera to observe the laser beam.
Any laser diode will be damaged by a large current or pulse. Avoid current surges and
electrostatic discharges. Safety grounding of the human body and all measuring equipment, jigs
and tools is absolutely necessary. T he use of a grounding mat on the workbench and floor is
necessary. Even a small electrostatic discharge from the human body may destroy the laser
diode instantaneously or reduce its life time.
The pins of the laser diode may be shorted at the factory by a solder bridge at the FPC for
protection during transportation and storage of the unit. If this is the case, open the short circuit
(accessible from the bottom side of the module) quickly with grounded soldering iron (less than
