Balanced detector


Balanced detector supporting a wide temperature range


This is a differential amplification type photoelectric conversion module containing two Hamamatsu photodiodes with balanced characteristics. The photodiodes are connected in a direction that cancels out the photocurrent of each photodiode. This configuration cancels out the common mode noise of the two incident light rays. The minute difference in light levels is treated as a displacement signal, converted into an electrical signal, and output. This product supports wide operating and storage temperature ranges. It can be applied to Doppler LiDAR, which measures wind speed and direction.

-Cutoff frequency: 200 MHz
