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.
A one dimensional PSD makes continuous detection of the position of a laser spot along one axis possible. It possesses three contacts. Customized PSDs available.
A two dimensional PSD makes continuous detection of the position of a laser spot along two axes possible. It possesses four contacts. Customized versions available.
Phototransistors have a sensitivity to light that is magnitudes higher than conventional PSDs.
SPC PSDs are position sensitive detectors with integrated signal processing circuitry.
PSDs as alternative to scanning systems.
Thanks to the small areas of the individual segments differential diodes are well suited for high resolution and fast position measurements.
One dimensional silicium detector arrays with 12, 16, or 32 single elements
The four-quadrant diode JQC5R covers a spectral range from 215 to 360 nm.
PSM: Position Sensitive Modules. PSDs mounted in a housing as a complete unit.
