(1)
Class 1 laser devices are safe under reasonably foreseeable operating conditions. In general they would not be expected to emit any radiation which is strong
enough to damage they eyes or the skin.
(2)
Under reasonably foreseeable operating conditions, Class 2 laser devices would not be expected to cause any permanent eye damage, provided that any
exposure can be terminated through the eyelid closing reflex (assumed to be 0.25 s).
(3)
Roughness results measured non-contact might not be identical compared with traditional systems due to different principles.
