Gentec-EO IS50A-1KW-RSi-INT-D0 Water-cooled Integrating Sphere Detector Description：

Datasheet(CN) Datasheet(EN) User's Manual

Gentec-EO IS50A-1KW-RSi-INT-D0 Water-cooled Integrating Sphere Detector for laser power measurement up to 1000 W.

Measure from low powers to the multi-kilowatt level with a single device

The broad dynamic range and very low noise equivalent power (NEP) of the IS integrating spheres provide users the ability to measure several lasers with different average powers with only one device.

Outstanding signal-to-noise ratios (SNR)

No need to change detector or manage attenuation when the measured power spans a wide range

Lower initial and maintenance costs compared to buying multiple detectors to cover the same range

Monitor high-power lasers at high speed

Thanks to their photodiode-based sensor, power meters of the IS series measure in under 200 ms, tens of times faster than with thermal detectors.

Faster measurements: no need to wait for the detector to stabilize

Discern quick changes in laser power

Follow the ramp-up of high-power sources

Increased productivity
