Biased Photodetector Modules

Self-contained biased detector modules that simplify system integration — combining stable bias circuitry with optimized photodiode performance.

DET20 series bias photodetector for mW level optical power detection, using free space light input, the series of photodetectors without amplification circuit, with very low noise, the module using analog signal output.
