Safety of Laser light
 Laser Light can damage 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.
