PSD Electronics
⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Extremely versatile - all important parameters can be adjusted
- Highest performance - 16 bit A/D conversion at 1 MHz and full speed USB data transfer
- User friendly - intuitive interface based on LabVIEW
- Suitable for all users - easy set-up and advanced analyzing functions included
SEEPOS - A versatile PSD signal processing tool perfect for development of PSD systems
For most position measurement applications the SiTek SEEPOS system offers a complete and easy-to-use solution. High speed PSD electronics combined with digital signal processing and high speed USB data transfer gives a powerful measurement system. With its large dynamic range it can handle light powers from nW to mW from DC light sources as well as modulated light sources. All parameters, such as PSD bias voltage, amplifier gain, the use of analog and digital filters etc., are easily controlled from the included software and light spot position is continuously displayed both in XY and X-t, Y-t graphs. Optimized plot algorithms ensure that all data is visually seen on the screen even in full speed measurements. Included tools for data analysis and visualization simplify rapid scan through large data sets in order to find specific parts of interest.

SiTek SPC-PSD (Signal Processing Circuit)
In order to facilitate the operation of our PSDs, we have developed a dedicated 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 Evaluation Board
In order to simplify the set up of our popular SPC-PSDs 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 of the SPC-PSD easily accessible.
Evaluation boards for both the J-lead and the DIL version of the SPC-PSD are available and, as all of our products, they are of course RoHS compliant.
