The PD610 is a photodetector with amplification circuitry for free-space optical systems. The unit includes a photodiode, transimpedance amplifier, and RF connector packaged in an aluminum housing.
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.
The DET30 bias photodetector is a compact, unamplified, fiber-optic input, battery-powered detector with very low noise, and can be used to detect optical signals with ps-level pulse widths.
