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.

Cautions
(1) Operating method
The 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. 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 the optical output power generated by spike current when switching on and off does not exceed the maximum
absolute 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
strap 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 Max Rating.
(4) Others
Nichia LDs described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment,
communications equipment, measurement instruments and household appliances). Consult Nichia’s sales staff in advance
for information on the applications in which exceptional quality and reliability are required, particularly when the failure or
malfunction of the LDs may directly jeopardize life or health (such as for airplanes, aerospace, submersible repeaters,
nuclear reactor control systems, automobiles, traffic control equipment, life support systems and safety devices).
The Purchaser must acknowledge that any LD can be failed statically and must design its equipments fail safe design. Prior
to use of the LD, please confirm that the LD, as described in Nichia’s specifications, meets the life expectancy needs of, and
provides the features required by the Circuit and any related modules, equipment and/or systems.
Due to its short wavelength and high optical output power, optical depositions on optical path may occur depending on
surrounding conditions. Appropriate design or countermeasures should be used to avoid optical depositions.
Nichia prohibit Purchaser from reverse engineering, disassembling, or taking any other steps to derive the structure or
design of the LD.
The appearance and specifications of the product may be modified for improvement without notice. The formal
specifications must be exchanged and signed by both parties before large volume purchase begins.
No unauthorized transmission or reproduction of this document, either in whole or in part, is permitted.
