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.

Tiny Jack for Height Adjustment

Our Model 9201 Tiny jack is especially useful for aligning the height of this free space optical receiver to the optical beam.

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.
