Balanced Optical Receiver, InGaAs, 900-1700 nm, 800 MHz, Free Space

The 1617-AC-FS InGaAs 800 MHz Balanced Optical Receiver is ideal for FM spectroscopy, absorption spectroscopy, or ellipsometry. This free space 900 to 1700 nm balanced photoreceiver can make all the difference when you're trying to see a small signal. They 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. M4 and 8-32 mounting threads.

An external power supply, which must be purchased separately, is required – we recommend our 0901 power supply. Power supply cables 0923 and 0924 are included with each receiver.
