Highly accurate filters with small f1' errors matching the CIE 1931 Standard Observer. Our Tristimulus filters are used in colorimeters and photometers across a wide range of industries including: Electronic Displays Automotive Aerospace Projection CIE Tristimulus Filters Designed for Your Unique Requirements Chroma Technology designs and manufactures customized filters that consider the response function of the detector and/or the spectral power distribution of a light source. We understand that every color measurement application has its distinct challenges. Whether you need filters matching the Standard Observer functions or your Customized functions, we’ve got your solution. That's why we offer comprehensive customization options for our tristimulus filters , ensuring they perfectly match your specific light source or detector requirements. Accuracy in Display Measurement Applications using colorimeters to measure color fidelity depend on highly accurate optical filters like Chroma Technology’s Tristimulus filters. Display to be measured Common display types include AMOLED, OLED and QLED but any light emitting display which can be calibrated should be measured. Accurate Filters In a colorimeter, light passes through the tristimulus filters which match the intended color matching functions. Chroma Technology also designs and manufactures Customized filters which take into account the response function of the detector and/or the spectral power distribution of a light source. Whether you need filters matching the Standard Observer functions or your own Customized functions, we’ve got your solution. Accurate Result Accurate filters increase the accuracy of the measurement of your display’s spectral power distribution, allowing you to accurately calibrate your display. Accuracy in Filter Manufacturing The smaller the f1' number, the more accurately the filter matches the intended response function. With highly accurate filters matched to your Customized functions, we make the corrections for you. Contact us to see what we can do for your application.
