OSI Optoelectronics offers a variety of products specifically designed for position sensing applications. These segmented and lateral effect position sensing detector (PSDs) are available in 1-dimensional or 2-dimensional active areas, as well as in a variety of active area sizes and packaging for an array of applications. The segmented detector is typically used in beam nulling applications while lateral effect PSDs are most suitable for measuring wide lateral displacement.
The SPOT Series are common substrate photodetectors segmented into either two (2) or four (4) separate active areas. Click here to view products and descriptions.
Sum and Difference Amplifier Modules
QD7-0-SD or QD50-0-SD are quadrant photodiode arrays with associated circuitry to provide two difference signals and a sum signal. Click here to view products and descriptions.
Duo Lateral PSDs
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. Click here to view products and descriptions.
Tetra Lateral PSDs
Tetra-lateral position sensing detectors are manufactured with one single resistive layer for both one- and two-dimensional measurements. Click here to view products and descriptions.
