Safety
2.2 Laser safety
2.2.1 Laser classification
The laser safety class indicates the risk potential from accessible laser radiation.
The laser system is a Class 2 (US: Class II) laser marking system as per IEC 60825-1 "Safety of Laser
Products".
Warning Laser
Laser radiation of Class 2 (US: class II)
For Class 2 (US: class II) laser is short term exposure (up to 0.25 seconds) harmless to
the eyes and can therefore be operated without additional protective measures. However it
can cause irritation of the eyes if the natural avoidance reaction (staring into the laser beam
deliberately) or eyelid closure reflex is suppressed.
– Do not suppress the eyelid closure reflex.
– Do not stare directly into the laser beam.
– Close eyes, turn away.
– Never look at the laser beam directly with an optical instrument, e.g. a lens.
Class 2 (US: class II)
The accessible laser radiation of Class 2 (US: Class II) laser systems does not pose any hazard for the skin.
Diffuse reflections as well as any short-term irradiation of the eyes (exposure time max. 0.25 seconds) also
pose no risk due to the low output power.
However, it is possible to suppress the natural eyelid closure reflex and stare into the class-2 laser beam for
a time long enough for the eyes to get injured.
