Four Quadrant Position Sensing Detector

Silicon Si four quadrant detector with large photosensitive surface 400-1100nm (photosensitive surface diameter 10/16mm)

The device is an N-type silicon quadrant detector, and when the radiation flux of light to each quadrant of the device is equal, the output photocurrent of each quadrant is equal. When the target deviates, the change in radiation flux between quadrants causes changes in the output photocurrent of each quadrant, which can measure the orientation of the object and play a role in tracking and guidance.
