Ambient Light Sensing

Nowadays’ Smartphones incorporate multiple optical sensors to measure light and color e.g. to adjust the device’s display backlight for better readability, power saving or for color-correction in images taken with the Smartphone camera.

Our customizable dielectric coatings allow the design of sophisticated filter characteristics for accurate ambient light- and color measurements, ideal for use in mobile devices and other consumer electronics.

The capabilities to pattern the filter coatings by means of Lithography gives optical designers the possibility to specify filters for multi-spectral measurements with several spectral bands from ultra-violet to visual to the near-infrared range of the light spectrum.
