Safety of Laser light
•
Laser Light can damage the human eyes and skin. Do not expose the eye or skin directly to
any laser light and/or through optical lens. When handling the LDs, wear appropriate safety
glasses to prevent laser light, even any reflections from entering to the eye. Focused laser
beam through optical instruments will increase the chance of eye hazard.
•
WARNING: Laserdiode is emitting invisible light
Cautions
1. Operating methode
• This LD shall change its forward voltage requirement and optical ouput power according to
temperature change. Also, the LD will require more operation current to maintain same ouput
power as it degrades.
• Confirm that electrical spike current generated by switching on and off does not exceed the
maximum operating current level specified herein above as absolute maximum rating. Also,
employ appropriat countermeasures to reduce chattering and/or overshooting in the circuit.
2. Static Electricity
• Static electricity or electrical surges will reduce and degrade the reliability of the LDs. It is
recommended to use a wrist trap or anti-electrostatic glove when handeling the product.
3. Absolute Maximum Rating
• Active layer of LDs shall have high current density and generate high electric field during its
operation. In order to prevent excessive damage, the LD must be operated striclty below
absolute maximum rating.
