The 2051-FC Adjustable Silicon Fiber-Optic Receiver is based on our popular Model 2001 photoreceivers. This higher speed FC optical input model features a low-noise 300 to 1050 nm Silicon detector, variable-gain transimpedance amplifiers, and two adjustable filters. The DC÷30 setting prevents your signal from going off-scale due to DC amplitude fluctuations, without attenuating fast signals. The high-pass filter can be adjusted to eliminate residual 60 Hz noise, and the independent low-pass filter can be set to dampen noisy signals. Variable gain of up to 90 dB in 10-dB steps gives you a useful input range from 1 pW to 10 mW. 8-32 mounting thread.
