Precautions
-
Do not
operate the device above the maximum rating condition, even momentarily.
It may cause unexpected permanent damage to the device.
-
Semiconductor laser device is very sensitive to electrostatic discharge.
High voltage spike current may change the characteristics of the
device, or malfunction at
any time during its service period.
Therefore, proper measures for preventing electrostatic discharge are
strongly recommended.
-
Effective
heat sink can help the device operates under a more relax condition; as a
result, a more stable characteristics and better reliability can be
achieved. So
it is recommended that always apply proper heat sink before the device is
operating.
-
Do not
look into the laser beam directly by bare eyes.
The laser beam may cause severe damage to human eyes.
-

specifications are subject to change without notice.
