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.
These LDs are classified in Class 4 of IEC60825-1 and 21 CFR Part 1040.10 Safety
Standards. It is absolutely necessery to take overall safety measures against User’s modules,
equipment and systems into which this LDs are incorporated and/or integrated.
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. In order to maintain output power, use of APC (Automatic Power
Control) is recommended. Which use monitor feedback to adjust the operation current.
• 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.
