SiTek SEEPOS: Sub-Micron Positioning – Plug-and-Play

The PSD signal processing and optimization tool SEEPOS, developed by SiTek, offers a complete and easy-to-use positioning 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 SEEPOS handles light powers from nW to mW, from DC and 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 s

oftware and light spot position is continuously displayed both in XY and X-t, Y-t graphs.
