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.
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.
