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
