ROF -BPR series of balanced light detection module (balanced photodetector)integrates two matching photodiode and an ultra-low noise transimpedance amplifier, effectively reducing the laser noise and common mode noise, improving the system’s noise ratio, having a variety of spectral response optional , Low noise, high gain, easy to use and so on, Mainly being used for spectroscopy, heterodyne detection, optical delay measurement, optical coherence tomography and other fields.
BPR series 200M and 350M high-gain balanced detection modules, with high gain and low noise characteristics, through two PIN tube response optimization to achieve high common-mode rejection ratio and high output voltage amplitude (~3.5V), this detection module can provide different gain and coupling output modes according to customer requirements. It is very suitable for coherent detection systems such as coherent Doppler wind radar.
