For The Safety Use Of Laser Product; Radiation Information - Panasonic LP-M Series Maintenance Manual

For the Safety Use of Laser Product

This product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifications of "Safety
of laser products" IEC 60825-1. Perform the safety protection measure before using the system. Refer to "Safety protection
measures for users" (P.19) for details.

Radiation information

„ 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 eyes. It is equal of
NHZ 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 maximum output power means the maximum value of output that can be output from a laser oscillator itself.
Refer to "1-3 Specification" (P.30) for details of average output.
*2 : The pulse duration means the available output range from the laser oscillator itself.
*3 : "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.
*4 : MPE in this table is a value calculated with exposure time set to 10 seconds.
„ Guide laser 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."
