The 2051-FS-M Adjustable Silicon Optical Receiver is based on our popular Model 2001 photoreceivers. This higher speed free space optical input model features low-noise 300 to 1050 nm Silicon detectors, 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. M4 mounting thread.
An external power supply or two 9-V batteries are required. Two batteries are included with the product, but a power supply and cables must be purchased separately. We recommend our
