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.
