Position Sensing Diodes (PSDs)

The OT-302D Display Module brings a new level of ease and sophistication to display and analysis of position sensing data collected from the OT-301 Position Sensing Amplifier. Utilize the module in three ways: as a standalone readout system, in tandem with Beamtrak data processing software (included), or with... Read more

The OT-301 Position Sensing Amplifier is the easiest, most precise way to process the current output from any position sensing detector (PSD) on the... Read more

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...

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... Read more

The standard product line PSD’s meets most market requirements. However, there is no doubt that a customised PSD will ensure the best performance from your product whether it be an instrument or a complex measurement system. There are several parameters that we can optimise to get the best performance for your... Read more

The SiTek Two-dimensional PSD (Position Sensing Detector) has high resolution, fast response and outstanding linearity. The spectral range covers the region 400 – 1100 nm. Thanks to SiTek’s proprietary AR-coating, optimized around 860 nm, a reflection loss of only 2% is achieved around the responsivity... Read more

The SiTek One-dimensional PSD (Position Sensing Detector) has high resolution, fast response and outstanding linearity. The spectral range covers the region 400 – 1100 nm. Thanks to SiTek’s proprietary AR-coating, optimized around 860 nm, a reflection loss of only 2% is achieved around the responsivity peak. There is... Read more
