Position-sensitive diodes (PSD)

These components utilize the effect of the lateral division of the generated photocurrent. The term "position sensitive detector" (PSD) refers to a component that is based on silicon PIN diode technology and is used to measure the position of the integral focus of an incoming light signal. A light spot on the PSD, for instance, is converted into a continuous electrical signal corresponding to the focal position of this spot. The position of a direction is derived from the relationship between two output currents.

Special features
  • One-dimensional PSD
  • Two-dimensional PSD
  • Duo-lateral PSD
  • High position resolution
  • High linearity
  • Components with up to 20 mm measuring range in two directions
