Safety of Laser light



Laser light can damage the human eye and the eyes of
animals. Do not look at any laser light directly or through

any optical lens. When handling a laser diode, do not look
directly at the light generated by it. Wear appropriate safety
glasses to prevent light from entering the eye by reflection off
of another surface.



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.



Operating method



Laser diodes are to change forward voltage and light output power due to the fluctuation in
temperature etc. They have some tendency to gradually increase electric current necessary to
keep the output power constant during their operation. When precise optical output control is
required, it is recommended to use an external photo diode to monitor output power and use
APC (Automatic Power Control) function in the operating circuit.



Cautions on LD handling



Static Electricity and surge damage the LDs. It is recommended to use a wrist strap or anti-electrostatic glove
when handling the Product.



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 specifications of the Product may be modified for improvement without prior notice. The formal
specifications must be exchanged and signed by both parties before a user starts mass production.



Strictly prohibited are reverse engineering and disassembly concerning, but not limited to, structure and
composition of the Product.



Caution-use of controls or adjustments or performance of procedures other than those specified herein may
result in hazardous radiation exposure.
