Customised PSD (Position Sensing Detector) – SiTek

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

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 application.

Customisable Parameters

The detector geometry is the basis for most of the other parameters, can be of any shape and size within the 3″ wafer diameter. Resolution, rise time, detector resistance, noise and capacitance are connected with the physics of the PSD and are co-related with each other and with the size. Nevertheless, optimisation for a special need is possible and we are able to tailor-make the parameters within the physical limitations. The spectral response can be optimised for any desired wavelength between 200-1100 nm with the highest possible responsiveness. Last, but not least, the assembly of the PSD can be tailored. Size, number of pins, spacing of the pins, type of cover glass, AR-coating, optical filters etc. are all specifications for the package which may be adjusted.
