Please could someone clarify the Laser Class of the 81663A DFB Laser source. The sticker on the unit itself says Class IIIb (serial DE40400420) but the most recent documentation states it is Class 1M. Which is it? and why would the classification have been changed? could it be that older versions of the instrument were Class IIIb but newer revisions of the instrument are now Class 1M?


From a H&S point of view we need to know for sure which classification it is so that we can take the appropriate precautions.
