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
