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. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice www.roithner-laser.com -3- 12/05/14
