Duo Lateral PSDs

One and Two-Dimensional Photodiodes (Vbias=-15V): Metal Package

Download Datasheet Technical Support

The Super Linear Position Sensors 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 continuos position sensors, these detectors are unparalelled; offering position accuracies of 99% over 64% of the sensing area. These accuracies are achieved by duo-lateral technology, manufacturing the detectors with two seperate resistive layer, one located on the top and the other at the bottom of the chip. One or two dimensional posion 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. For position calculations and further details on circuit set up, refer to the "Photodiode Characteristics" section of the catalog. The maximum recommended power density incident on the duo lateral PSDs are 1 mW / cm2. For optimum performance, incident beam should be perpendicular to the active area with spot size less than 1mm in diameter.
