10 MHz Adjustable Optical Receivers

Just like their lower-frequency counterparts, these 10 MHz optical receivers are the ideal free space optical front ends for systems requiring low-noise input. They have been engineered to eliminate most common sources of noise and drift, and have enough gain to pick up even very weak signals.

Features

Silicon or InGaAs Versions

The silicon models (2051) provide wavelength coverage from 300-1050 nm, and InGaAs models (2053) provide coverage from 900-1700 nm. These detectors are available in the free space design as well as the fiber receptable design.

10 MHz Versions of our Popular 200 kHz Photoreceivers

In response to customer requests, we’ve extended the bandwidth of our popular 200 kHz photoreceivers to 10 MHz to provide faster photodetection for our customers.

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 10 MHz to 1 MHz.

Adjustable High and Low Pass 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.

Flexibility for a Wide Range of Applications

The ﬂexibility and high performance of these photoreceivers means that they can be used in a wide range of applications. Use them as low-noise DC-coupled photoreceivers/preamplifiers in servo-control systems requiring near-zero phase shifts. Or use them in lock-in amplifier systems to take advantage of their shot-noise-limited performance and 90-dB maximum gain.
