(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 the LD Modules, 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
• OD (Optical Density) :
• Visible Light Transmission: > 20%
This LD 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 LD Modules are
incorporated and/or integrated.
(2) Operating method
This LD Modules may 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 Modules. When working with
the LD Modules, take countermeasures to avoid the generation of static electricity.
(4) Absolute Maximum Rating
Active layer of the LD Modules shall have high current density and generate high electric field during its operation.
In order to prevent excessive damage, the LD Modules must be operated strictly below Absolute Max Rating.
The LD Module 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 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 prohibits Purchaser from reverse engineering, disassembling, or taking any other steps to derive the structure
or design of the LD Modules.
The appearance and specifications of this LD Module may be modified for improvement without notice. The formal
specifications must be exchanged and signed by both parties before large volume purchase begins.
