Wavelength-sensitive diodes (WS)

Wavelength-sensitive photodiodes utilize the effect of the wavelength-specific absorption depth of radiation in silicon. For this purpose, two p-n junctions are aligned vertically in the silicon crystal, thus enabling separate signal detection within vertically adjacent ranges. Such a configuration is particularly useful for the wavelength detection of monochromatic input signals. The calculation then merely requires the formation of a quotient between two photocurrents. The calculation of a color temperature from a non-monochromatic input signal requires two such detectors and an additional optical filter.

Special features
  • Two vertically aligned p-n junctions
  • Measuring range: 450-950 nm
  • Particularly suitable for monochromatic light
