Fiber Laser Marker MX-Z2000H-V1 series User’s Manual (Z416)
Summary of safety measures requirements for users (JIS C6802 2014)
*1:
MPE (Maximum Permissible Exposure)
Maximum value of the level of laser irradiation to which a person may be exposed without hazardous effects in a normal environment.
Note: The table lists the required elements for your convenience.
Class 4 laser (processing laser)
Class 4 lasers are defined to "have a possibility of causing acute vision disturbances and skin damage with direct and scattered
beams and causing a fire".
*1:
Maximum output refers to the maximum power of the laser beam that the device may output under all operating conditions including during a single point of failure. (The
maximum output may exceed the highest output during normal operation.)
*2:
Indicates the distance from the source at which the beam radiation intensity or radiation exposure becomes equal to the maximum permissible exposure for the cornea.
*3:
The value is calculated with the exposure time set to 10 seconds.

NOHA
Indicates an area where the laser beam radiation intensity or radiation exposure
exceeds the maximum permissible exposure. The maximum hazard distance and range
are the same as a sphere that has the radius of NOHD. It changes according to the
workpiece reflectance and surface conditions. Calculate the value taking the actual
usage conditions into consideration.
