Gentec-EO UP19K-50L-W5-D0 Thermal detector for laser power measurement up to 50 W.

Measure extremely high average power density lasers with the W absorber

The W absorber can handle tightly focused beams thanks to its extremely high average power density damage threshold of 100 kW/cm2. It measures from UV to IR but is not suitable for CO2 laser wavelengths.

Ideal for UV lasers and tightly focused beams

Very low risk of damaging the equipment

Faster measurement with XNR Anticipation

Measure laser power up to 10x faster (model-dependant) with XNR AnticipationTM. Our proprietary algorithm looks at the rate at which the signal increases or decreases and combines this with calibration data to predict the result. The measurement is therefore calculated and displayed faster than the natural response of the detector.

Save several seconds to tens of seconds for each measurement

Shorter operation interruption

Faster laser output diagnostics

Increased productivity

No compromise on measurement accuracy

Optional INTEGRA (USB or RS-232) output

When you choose the INTEGRA output option you get an all-in-one measurement instrument that combines both the detector and the meter in one convenient product. Plug the detector in your PC, install our free software and start measuring.

The most cost-efficient solution

Same measurement performance as our other solutions

No compromise on interface functions and features

Compact solution for OEM applications and field servicing

Save money on recalibration with an all-in-one instrument
