Cautions
(1) Safety of Laser light
Laser light can damage the human eye and skin.
Do not expose the
eye or skin to any laser light directly or through any optical lens. When
handling LD Slot Module, 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. The following specifications
are required of the safety glasses.
• Wavelength : 300nm�½�500nm
• OD (Optical Density) : > 4
• Visible Light Transmission: > 20%
Nichia LD Slot Module is classified in
Class 4 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 LD Slot Module is incorporated and/or integrated.
(2) Operating method
LD Slot Module is to change light output power due to the fluctuation in temperature etc. It has some
tendency to gradually increase electric current necessary to keep the output power constant during its
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.
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.
(3) Static Electricity
Static electricity or electrical surges will reduce and degrade the reliability of the LD Slot Module. When
working with the product, take countermeasures to avoid the generation of static electricity.
(4) Absolute Maximum Rating
Active layer of LD Slot Module shall have high current density and generate high electric field during its
operation. In order to prevent excessive damage, the LD Slot Module must be operated strictly below
Absolute Max Rating.
(5) Others
LD Slot Module described in this brochure is intended to be used for ordinary electronic equipment (such as
printer, exposure devices, etc). 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
Slot Module 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 prohibits Purchaser from reverse engineering, disassembling, or taking any other steps to derive the
structure or design of the LD Slot 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.
