Photodiode Receiver Modules

Our receiver modules simplify electro-optical system integration by combining a detector with dual-gain pre-amplifier circuitry in a compact package. By optimizing both in a single unit, electromagnetic interference is minimized without sacrificing package size or convenience. The built-in pre-amplifier electronics allow direct voltage readout of any UV, visible, or NIR source with an oscilloscope or data acquisition (DAQ) system. Applications include spectroscopy, camera triggering, laboratory experimentation, and industrial OEM integration. UV and VIS detectors are silicon; NIR detectors are InGaAs, PbS or PbSe. PbS and PbSe detectors require a modulated infrared signal for operation. Thermo Electrically Cooled options have improved temperature stability as well as higher signal to noise ratio. Signal is output via BNC connector and operating temperature is 22°C. DB-9 cable for use with power supplies (see below) is included. BNC cable available separately. Responsivity, noise, and bandwidth specifications are given for low / high settings.
