Product information "Duo-lateral Position Sensing Detectors"

OSI Optoelectronics’ super linear duo-lateral position sensing detectors (PSDs) feature state of the art duo-lateral technology to provide a continuous analog output proportional to the displacement of the centroid of a light spot from the center, on the active area.

As continuous position sensors, these detectors are unparalleled, offering position accuracies of 99% over 64% of the sensing area. These accuracies are achieved by duo-lateral technology, manufacturing the detectors with two separate resistive layers, one located on the top and the other at the bottom of the chip. One- or two-dimensional position measurements can be obtained using these sensors.

A reverse bias should be applied to these detectors to achieve optimum current linearity at high light levels. The maximum recommended power density incident on the duo-lateral PSDs is 1 mW/cm2. For optimum performance, the incident beam should be perpendicular to the active area, with a spot diameter of less than 1 mm.
