6Cautions in Handling Laser BeamThis product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifications of IEC60825-1 “Safety of laser products”.Class 4 laser refers to “Laser products for which intrabeam viewing and skin exposure is hazardous and for which the viewingof diffuse reflections may be hazardous. These lasers also often represent a fire hazard.”Perform the safety protection measure before using the system. Refer to “Safety Protection Measures” (P.8) for details.*1:The maximum output is the maximum value that the laser oscillator outputs laser beam.This product is set to 10W as the average output of laser oscillator. Moreover, the optical power emitted from the lasermarker is decreased further.*2:NOHD represents the distance from the light source of laser beam, where the amount of beam irradiance or radiantexpposure is equal to the maximum permissible exposure to eyes.*3: MPE means the assumed exposure duration for determination of the value. The value colculated on 10 seconds.■Laser Radiation RangeUnit: mmItem Specification RemarksWave Length 10.6μm Invisible beamLaser Medium CO2 -Max.

It is equal to the value ofNOHD at a maximum.NHZ varies depending on the reflectance or surface con-dition of works.
