Series Radiometers/Joulemeters

These small, modular detector probes and instruments are ideal for the lab bench, production test bed or on board your laser. Select Si, Ge and InGaAs photodiodes or Pyroelectric detectors to cover the spectrum from DUV to FAR IR and even the THz region. Plug the probes into an analog power supply (APM) for use with oscilloscopes and lock-in amplifiers, or plug them into a digital USB-based electronic module (DPM) for powerful PC control. LabView software and drivers provide dual channel and single channel measurement. Measure from fJ to mJ and pW to mW.

Temperature Controlled, Ultra-Stable Pyro Radiometer

This ultra-precise radiometer employs a large area, broadband pyroelectric hybrid detector packaged with a single-stage TE Cooler to control its temperature to 0.05° C from 20 to 30° C. As a result, the voltage response of the STEP-45 probe is stable to 0.01% over the same temperature range. Further, a black absorbing coating is spectrally flat from 0.25 to 15µm. The system is an excellent IR calibration standard for broadband or spectral measurements. Measure from 10 nW to 10 mW.
