Cautions

(1) Safety of Laser light

Laser light can damage the human eyes and skin. Do not expose the eye or skin

to any laser light directly and/or through optical lens. When handling the LD

Receptacle Modules, 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.

These LD Receptacle Modules are classified in Class 4 of the 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

LD Receptacle Modules are incorporated and/or integrated.

(2) Operating method

The LD Receptacle Module shall change its forward voltage requirement and optical output power according to

temperature change. Also, the LD Receptacle Module will require more operation current to maintain same output

power as it degrades.

Confirm that electrical spike current generated by switching on and off does not exceed the maximum operating

current level specified herein above as absolute max rating. Also, employ appropriate countermeasures to reduce

chattering and/or overshooting in the Circuit.

ACC (Auto Current Control) mode is recommended for the Product operation. Also, please be careful for the

overshooting in order to avoid excessive optical output power as the laser operation is started.

(3) Static Electricity

Static electricity or electrical surges will reduce and degrade the reliability of the LD Receptacle Modules. It is

recommended to use a wrist strap or anti-electrostatic glove when handling the Product.

(4) Absolute Maximum Rating

Active layer of LD Receptacle Modules shall have high current density and generate high electric field during its

operation. In order to prevent excessive damage, the LD Receptacle Module must be operated strictly below Absolute

Max Rating.

(5) Others

Nichia LD Receptacle Modules 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 LD Receptacle Modules 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).

Nichia prohibit Purchaser from reverse engineering, disassembling, or taking any other steps to derive the structure or

design of the LD Receptacle Module.

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.
