Laser Licence

Hi Leonie,

I believe it should be looked at this way: While your lasers are Class 
IV (potentially hazardous and regulated), you are not operating a 
"laser", you're operating a flow cytometer.  If the beams are contained 
behind safety interlocks that are operating as designed by the 
manufacturer and not being defeated, it becomes a Class I device which 
is unregulated.

There's some more info at

(Look down the page to where "Class1" is shown).

Regards & good luck,
