Laser Radiation Information - Panasonic LP-RV Series Safety Manual

Laser Radiation Information

This product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifications of IEC
60825-1 "Safety of laser products". Perform the safety protection measure before using the system. Refer to "Safety
Protection Measures for Users" (P.29) for details.
Marking Laser (Class 4)
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."

NHZ represents the area where the amount of beam irradiance or
radiant exposure exceeds the maximum permissible exposure to
NHZ eyes. It is equal of NOHD at a maximum.
NHZ varies depending on the reflectance or surface condition of
works. Please calculate it based on the actual working environment.
*1 : The wavelength, maximum output power, and pulse duration in this table indicate the maximum value that can be
output from a laser oscillator itself. For the specifications under the normal operation, refer to "Setup/Maintenance
Guide".
*2 : "NOHD" means the distance that the area where the amount of beam irradiance or radiant exposure becomes equal
to the maximum permissible exposure to eyes.
*3 : MPE in this table is a value calculated with exposure time set to 10 seconds.
Guide Laser and Pointer (Class 2)
The laser classified into the Class 2 refers to "Laser products that emit visible radiation in the wavelength range from 400
nm to 700 nm that are safe for momentary exposures but can be hazardous for deliberate staring into the beam."
