The 2317NF Large Area Adjustable Gain Balanced Photoreceiver takes the headache out of aligning and re-aligning your 800-1700 nm beams onto the photodetector. Ideal for FM spectroscopy, absorption spectroscopy, or ellipsometry, these balanced photoreceivers 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. 8-32 mounting thread. M4 metric adaptor and tool now included.

An external power supply or a 9-V battery is required. A battery is 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).
