23Radiation Information [LP-V/LP-W Series]⿎ Marking Laser (Class 4)Class 4 laser refers to “Laser products for which intrabeam viewing and skin exposure is hazardous and for which theviewing of diffuse reflections may be hazardous. These lasers also often represent a fire hazard.”Model Name LP-V10U LP-V15U LP-W052U RemarksWavelength 1060nm Invisible beamLaser Medium Yb:FIBER ―Max. Output *1 40 W 7.5 W ―Mode of Operation Pulsed CW(continuous wave) ―Pulse Cycle 10 μs to 50 μs ― ―Pulse Width *2 1 ns to 1000 ns ― ―Class 4 ―NOHD *3 35.8 m 65.9 m 21 m Nominal ocularhazard distanceMPE *4 50 W/m2MaximumPermissibleExposureNHZNHZ represents the area where the amount of beam irradiance or radiantexposure exceeds the maximum permissible exposure to eyes. It is equal ofNOHD at a maximum.NHZ varies depending on the reflectance or surface condition of works.Please calculate it based on the actual working environment.Nominal hazardzone*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.36) for details of average output.*2 : The pulse width 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 equalto the maximum permissible exposure to eyes.*4 : MPE in this table is a value calculated with exposure time set to 10 seconds.⿎ 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 400nm to 700 nm that are safe for momentary exposures but can be hazardous for deliberate staring into the beam.”Model Name LP-V/LP-W series RemarksWavelength 655nm Visible beamLaser Medium Semiconductor Laser -Max.
