Features

Silicon or InGaAs Versions

The silicon photodetector version has a 0.9 mm diameter PIN detector that provides wavelength coverage from 300-1050 nm.  The InGaAs photodetector version has a 0.3 mm diameter PIN detector that provides wavelength coverage from 900-1700 nm.

Adjustable high-pass and low-pass filters

Independent control of the low and high-frequency corners allows you to reject unwanted noise effectively. The single-pole filters provide a slope of –6 dB/octave with less than 90° phase shift. 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. The upper left knob adjusts the low-frequency corner and the upper right knob adjusts the high-frequency corner. The corner frequency increases by a factor of three with each full clockwise turn. The photoreceivers have ten settings for each frequency corner, creating a wide variety of frequency responses.

Fiber Alignment Application

A Model 2001-FC photoreceiver is being used in conjunction with our Model 9131 fiber aligner to optimize the coupling efficiency of the incoming laser light into an optical fiber.

Variable-gain Transimpedance Amplifier

Variable gain of up to 90 dB in 10-dB steps gives you a useful input range from 1 pW to 10 mW. For small signals requiring 80-dB or greater gain, the maximum bandwidth is reduced from 200 kHz to 20 kHz.

Flexibility & High Performance for a Wide Range of Applications

Use them as low-noise, DC-coupled photoreceivers/preamplifiers in servo-control systems requiring near-zero phase shifts at up to 100 kHz. Or use them in lock-in amplifier systems to take advantage of their shot-noise-limited performance and 90-dB maximum gain. By correlating their output voltages to a calibrated power meter, these photoreceivers can also be used as sensitive power sensors.
