Adjustable Balanced Receiver, 320-1000 nm, 10 MHz, Free Space

Please note that this product will be phased out by end of 2023. The recommended replacement is 2107-FS-M.

The 2107-FS Adjustable Gain and Bandwidth Balanced Optical Receiver is a free space, 300 to 1070 nm photoreceiver with higher-gain and lower-bandwidth than our popular Model 20X1 laboratory photoreceivers. Ideal for FM spectroscopy, absorption spectroscopy, or ellipsometry, this Silicon 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. 8-32 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 power supply with either or power cable (all sold separately).
