(SCI425CMA) Large Area Reference Detector

Sku: 126-9001

Quick Overview

Sciencetech's proprietary wideband detector design comes packaged in our standard "hockey puck" enclosure (2" diameter x 1" high) and is connectorized to be powered directly from the Stanford SR-810/830 type lock-in amplifiers and optimized to utilize the full input range of these lock-ins as a reference detector for Spectral Response, Quantum Efficiency, Constant Photocurrent Measurement in Photovoltaic Testing Systems.
Features of our SCI425CMA:
This detector is not hygroscopic and may be operated indefinitely under normal atmospheric conditions and at temperatures beyond 100oC. A selection of windows is available to limit spectral response.
Calibration is supplied with the detector.
Element size: 5 mm dia.
Spectral response: (no window, blackened): 180nm – 2.5 microns (Quartz Window)

Availability: In stock
