APX00M3
Optical Detector with Four-Quadrant Position Sensing APD
APX00M3 consists of the Albis four-quadrant APX00M4 avalanche photodiode (quad APD) chip packaged in a TO-8 header and capped with a flat window TO-cap. Each individual quadrant of the APD is bonded to a separate pair of pins of the TO-header providing access to the individual anode and cathode of each APD segment.
The quad APD chip APD00M4 features a large active area, small quadrant separation and high responsivity in the wavelength range from 850 nm to 1650 nm. The topside illuminated chip is optimized for position sensing and optical beam tracking applications.
