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 ultra violet light which can be hazardous to the human
eye. This diode is classified as Class 3B laser product according to IEC 60825-1 and 21 CFR Part
1040.10 Safety Standards. Actual laser light emitted and precautions necessary strongly depend on
mode of operation.
