LASER SAFETY
The ProX 950 uses a UV (Ultra-violet) solid-state frequency tripled Nd:YVO4 laser which utilizes a 354.7 nm wavelength laser in
each IPM.
The ProX 950 is a
Class I
Laser product. Class I products are not considered harmful and require no special safety precautions,
under normal operating conditions. The Laser beam is completely confined. The viewing windows in the Process Module, block
the UV Laser radiation from exposure outside of the print area(s).
RADIATION: Operating the equipment or performing procedures other than those specified within this guide
may result in exposure to hazardous, invisible Laser radiation .
RADIATION: Never stare directly into a Laser beam, nor into any beam reflection, whether diffused or from a
mirrorlike surface .
RADIATION: During normal operation, and with all panels installed, the ProX 950 is classified as a Class I Laser
device . If any of the interlocks are defeated, the ProX 950 becomes a Class IV device . Eye damage can occur by
looking directly into the beam or by viewing any type of beam reflection.
RADIATION: Interlocks are to be defeated only by trained personnel when needed during service procedures .
