** FWHM < 1nm
*** Monitor Current may increase or decrease up to 3% in 24 hours.
If your application requires precise output power control, monitor current should not be used as reference for
output power. Use additional external PD to monitor output power.
All figures in this specification are measured by Nichia's method and may contain measurement deviations.

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