One-dimensional PSD (Position Sensing Detector) – SiTek

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 also an UV version available. The UV PSD is a detector optimized for use in the UV wavelength region 200-400 nm, although its spectral response reaches up to 1100 nm.


One-dimensional PSD features

  • converts the position of a light or radiation spot into signal currents
  • outstanding position resolution and linearity
  • wide range of spectral response
  • works with a wide range of light or radiation intensities
  • fast response time (1 MHz!)
  • measures light or radiation intensity and position simultaneously
  • independent of light or radiation spot focus
  • high dynamic range
