Position Sensitive Detectors

A one dimensional PSD makes continuous detection of the position of a laser spot along one axis possible.

A two dimensional PSD makes continuous detection of the position of a laser spot along two axes possible. I

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 silicon detector arrays with 12 single elements. Custom variants also available upon request.

The four-quadrant diode JQA5 covers a spectral range from 205 to 355 nm.

Compact one or two-dimensional PSD modules with a mount for high-precision position measurements.

Amplifiers for PSDs, Differential Diodes, and Quadrant Diodes
