Cautions
(1) Safety of Laser light
Laser beam are extremely dangerous to human eyes.
Never look at laser
beam 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.
Nichia LDs are classified in
Class 3B 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.
(2) 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.
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.
(3) 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.
(4) Absolute Maximum Rating
Active layer of LDs shall have high current density and generate high electric field during its operation.
prevent excessive damage, the LD must be operated strictly below Absolute Max Rating.
In order to
(5) 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.
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.
