PSD

Position sensitive detectors. Spatially-resolved photodiodes measure the position of a light spot. The bandwidth and resolution of so-called position sensitive detectors (PSDs) are unmatched.

Silicon-Differential and Quadrant Diodes

Thanks to the small areas of the individual segments differential diodes are well suited for high resolution and fast position measurements.

PSD

Differential diodes consist of two, quadrant diodes of four individual photodiode segments which are separated by only a very small gap of just several tens of μm.

Applications
Thanks to the small areas of the individual segments differential diodes are well suited for high resolution and fast position measurements along an axis, quadrant diodes along two axes. The position measurement is achieved by the comparison of the photocurrents of each photodiode segment.
