All figures in this specification are measured by Nichia's method and may contain measurement deviations.
Diffractive feedback efficiency to the Laser diode must be limited less than 20 % under the External cavity configuration.
This model is Test Sample for evaluation or design purpose only. Life time is not guaranteed.
The above specifications are for reference purpose only and subjected to change without prior notice.
Safety of Laser light
Laser Light can damege the human eyes and skin.
Do not expose the eye or skin to any
laser light directly 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 necessary to take overall safety measures against User's
modules, equipment and systems into which Nichia LDs are incorporated and/or integrated.
