*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.
Laser Information
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.

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.

Required for
non-visible
radiation.
Indicates that
laser is being
emitted in
non-visible
wavelengths.
Same as class
Terminate the beam at an end of an effective length.
3B
Avoid unintended reflection.

Required
Connect to the room or the door

Unlock when not in use.
Avoid inadvertent emission when in
use.
Indicates that laser is being emitted.
Follow the safety measure
described on the warning sign.
Required when the technical and
administrative procedures cannot be
executed, and when the laser level
