Lock-in Amp Detector, Pyroelectric, 100 nW - 100 mW, 8 mm

Model LIAD-PY-100M lock-in amplifier detector measures power of very low level CW or quasi CW sources. It uses a pyroelectric sensor in conjunction with an 18Hz chopper, which comes with the detector, to measure a wide range of radiation, from < 100 nW to 100 mW. It has an 8mm aperture and covers the broad spectral range from 0.15µm to 12 µm. You must use one of the compatible power meter models as a monitor, which include 1919-R, 843-R, 843-R-USB, and 841-PE-USB. To maintain calibration uncertainty and guarantee performance, we recommend annual recalibration.
