  1. SciPuck Detector

    (SCI420BJ-0) Pyroelectric Repetitive Pulse Energy Sensor

    Sciencetech’s SCI420BJ-0 wide-band pyroelectric detector is capable of measuring the amount of energy in nanosecond and picosecond pulses. We expect that it is possible to measure femtosecond pulses, but this has not yet been tested. The detector is windowless and a selection of windows is available to limit the spectral response. The SCI420BJ-0 is not hygroscopic and may be operated indefinitely under normal atmospheric conditions and at temperatures above 100°C. Sciencetech's proprietary SCI420BJ-0 detector is mounted in our standard 1" high and 2" diameter "hockey-puck" style enclosure. The SCI420BJ-0 is connectorized to be powered directly from the Stanford SR-810/830 lock-in amplifiers and optimized to utilize the full input range of these lock-ins for FTIR applications.
