Product Info
Introduction
The BPD230 series balanced photodetectors utilize spatial light input and are suitable for coherent detection optics in spatial light paths.
The balanced photodetector contains two photodiodes and a low-noise transimpedance amplifier, where the two photodiodes are matched to each other for excellent common mode rejection ratio, and the detector subtracts the two detected signals to eliminate the common mode noise, so that small variations of the effective signal can be obtained from the interfering noise. The detector is available in two spectral ranges, 400-1000nm and 1000-1700nm.
