Cautions in Handling Laser Beam
This 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 viewing
of 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 laser
marker is decreased further.
*2:NOHD represents the distance from the light source of laser beam, where the amount of beam irradiance or radiant
expposure 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.

Maximum permissible exposure
NHZ
NHZ represents the area where the amount of beam irra-
diance or radiant expposure exceeds the maximum per-
missible exposure to eyes. It is equal to the value of
NOHD at a maximum.
NHZ varies depending on the reflectance or surface con-
dition of works. Please calculate it based on the actual
working environment.
