Application information:
The inherent resolution of a PSD is very good. It is proven to be better than one part in one million. The per-
formance of a PSD based measurement system is thus limited by its mechanical, optical and electrical components.
To get the best performance you have to consider:
• Modulated light source. Modulation makes it possible to avoid influence of other light sources.
• Stable temperature.
• Mechanical stable system.
• High optical resolution.
• High resolution in division of the sum- and difference signals.
Resolution, optical sensitivity and measurement speed are related to each other in the PSD measurement
system and you have to make the proper choices and tradeoffs for your system. Further information as schema-
tics of a recommended hook-up is obtainable from your local distributor or from SiTek Electro Optics AB.
SiTek PSD Position Measurement electronic boards:
For most position measurement applications the SiTek PM-kit offers a complete and easy-to use solution. It is
a series of general purpose, high performance, low-noise electronic boards designed for SiTek PSD. You can
easily build your own measurement system using our PM-kit. Further information is obtainable from your local
distributor or from SiTek Electro Optics AB.
