Gentec-EO IS50A-1KW-RMT-D0 High-power Joulemeter for laser energy measurement up to 1 kW average power.
Diffused back-reflections confined in an angular cone
While thermal detectors and water calorimeters diffusely reflect 10% to 15% of the incoming light in a Lambertian manner, integrating spheres of the IS series reflect only 6% to 12% more directionally through their optical aperture. This helps improve safety in the measurement environment by making it easier to deal with back reflections.
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
Key Features
High average power
The water-cooled joulemeters can handle high average powers.
Resistant coating
Our proprietary coating is designed to be strong. Its damage thresholds are orders of magnitude higher than any other "white" coatings on the market.
Precise calibration
The IS detectors have a NIST-traceable calibration for their entire calibrated spectral range.
CHOICE OF OUTPUT
The IS-RMT detectors are available with four output options:
Smart DB15 connector containing all the calibration data
INTEGRA with USB output (-INT)
INTEGRA with RS-232 output (-IDR)
INTEGRA with USB output and external trigger (-INE)
