PX00U3
Optical Detector with Four-Quadrant Position Sensing PD
PX00U3 consists of a PD00U4 four-quadrant photodiode (quad photodiode) chip packaged in a TO-5 header and capped with a flat window TO-cap.
The quad photodiode chip features a very large detecting area with a diameter of 1 mm. The photodiode is segmented into four individual quadrants with small separation of only 30 µm. The topside illuminated p-i-n structure offers a very low dark current and an excellent responsivity in the wavelength region from 980 nm to 1620 nm. This makes it ideally suited for position sensing, beam alignment / profiling and optical tracking applications.
