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. In order to prevent
excessive damage, the LD must be operated strictly below Absolute Max Rating.
(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 statistically fail and must design its equipments in a 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 prohibits 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.
This LD contains the one of candidate substance of SVHC (Substance of Very High Concern) specified in REACH
(Regulation, Evaluation, Authorization and Restriction of Chemicals) regulation. Nichia reports following information
on the basis of Article 33 (Duty to communicate information on substances in articles) in REACH.
