This single-channel photodetector and amplifier is ideally suited for laboratory SERF magnetometer implementations. The unit consists of a JFET first stage transimpedance amplifier and a fixed-gain second stage amplifier, with excellent total gain-bandwidth and very low overall noise. Four adjustable gain levels are available with high bandwidth.
