General presentation The PSD (Position Sensing Detector) is an opto-electronic device which converts an incident light spot into continuous position data. It provides outstanding resolution, fast response, excellent linearity for a wide range of light intensities and also simple operating circuits. 2L2_MP1 A standard Two-dimensional PSD with 12-pin TO-8 metal housing, ø 15,3 mm There are two main types of PSDs available, one-dimensional and two-dimensional. Position Sensing Detector (PSD) features - Converts the position of a light or radiation spot into signal currents - Outstanding position resolution and linearity - Wide range of spectral response - Works with a wide range of light or radiation intensities - Short response time - Measures light or radiation intensity and position simultaneously - Independent of light or radiation spot focus - High dynamic range « home
