Balanced Photoreceiver Selection Guide

A balanced photoreceiver consists of two well-matched photodetectors so that a small signal not subtracted is amplified. Balanced Photoreceivers are especially useful in applications such as absorption spectroscopy, or heterodyne detection— anywhere you have a weak signal and need to cancel out residual intensity noise. Specifically, Nirvana™, ideal for OCT and interferometric measurements, is designed to eliminate the problems associated with manually balancing the reference and signal beams. It has a built-in low-frequency feedback loop that auto-balance between signal and reference arms.
