SPC-PSD (Signal Processing Circuit) – SiTek

Any questions or would you like to order this product? Do not hesitate to contact us

In order to facilitate the operation of SiTek PSD’s, they have developed a dedicated SPC-PSD (signal processing circuit). All components necessary to obtain the sum and difference signals from a two- or one-dimensional PSD have been concentrated on a 20,5 x 20,5 mm2 thick film substrate.

SPC-PSD features

analogue voltage outputs of all sum and differential signals from one- and two-dimensional PSD’s
laser trimmed resistors
inputs for external adjustment of offset voltages
good thermal tracking
small size
allows custom designed specifications
evaluation board available

For more information on the applications of PSDs, read this PEO article.

SPC-PSD Evaluation Board

In order to simplify the set up of our popular signal processing circuits in an optical system SiTek now releases an SPC-PSD Evaluation Board.

The Evaluation Board can easily be mounted on an optical table by using a standard 2” filter holder or screwed to for example an XYZ stage by using M6 screws. The board includes offset compensation electronics and a 14-pin connector that makes the inputs and outputs easily accessible.

Evaluation boards for both the J-lead and the DIL version are available and, as all of our products, they are of course RoHS compliant.

Part. NoDescription: SE-0012SPC01 Evaluation Board, SE-0013SPC02 Evaluation Board
