psd1_sh.jpgPosition Sensing Detectors ""PSD" are silicon photodiodes that provide an analog output directly proportional to the position of a light spot on the detector active area. The PSD allows you to simultaneously monitor position and light intensity.

Features:

  • Superior Linearity
  • Better Than 99.95% Over 80% Of Active Area
  • Proven Analog Resolution Better Than 1 Part Per Million
  • Low Thermal Drift, Less Than 40 ppm/°C
  • Fast Response Time
  • Simultaneous Position And Intensity Measurement
  • Wide Spectral Range
  • Independent Of Light Spot Size
