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: Laser diode is emitting invisible light

Cautions

1. Operating method

• This LD shall change its forward voltage requirement and optical output power according to

temperature change. Also, the LD will require more operation current to maintain same

output 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 appropriate 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 handling 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 strictly below

absolute maximum rating.
