These filters are compatible with common display types, including AMOLED, OLED, and QLED, and they can be calibrated for and measured on virtually any light-emitting display.
Accurate Filters
A colorimeter sees the light passing through tristimulus filters, which match the intended color-matching functions. Chroma Technology designs and manufactures several customized filters that can accommodate the response function of the detector in use and/or the spectral power distribution of a specific light source.
The company offers solutions for whether an application requires filters matching Standard Observer or Customized functions.
