Balanced Fiber-Optic Receiver, Adjustable, 800-1700 nm, 10 MHz, M4

The 2117-FC-M Adjustable Gain and Bandwidth Balanced Fiber-Optic Receiver is an FC connectorized, 900 to 1700 nm photoreceiver with higher-gain and lower-bandwidth than our popular Model 20X1 laboratory photoreceivers. Ideal for FM spectroscopy, absorption spectroscopy, or ellipsometry, this InGaAs adjustable balanced photoreceivers can make all the difference when you're trying to see a small signal. It can even eliminate the need for lock-in amplifiers, enabling you to cancel out laser-intensity noise in any experimental setup that produces either a reference signal or balanced optical signals.

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 0901 power supply with either 0923 or 0924 power cable (all sold separately).
