Mounting Instruction
In order to maintain lifetime and stability of the laser diode it is essential to provide efficient heat
management. Heat dissipation is possible through the base plate only. For long time stable operation
proper contact between laser diode base plate and heat sink is mandatory
Safety Advice
This laser diode emits highly concentrated visible light which can be hazardous to the human eye.
This diode is classified as Class 3B laser product according to IEC 60825-1. Actual laser light
emitted and precautions necessary strongly depend on mode of operation.
