The CA-410 is the next step in this analytic technology. The enhanced accuracy of the XYZ filters, the CA-410 pushed its spectral sensitivity even closer to the color-matching functions defined by CIE in 1931. Recently, demands for higher-quality images and video have been growing among smartphone users, due partly to dramatic increases in communication speed. In response, manufacturers are accelerating the development of higher-resolution displays with improved contrast ratio and color reproduction, such as HDR displays. As a result, manufacturers of such displays require a color analyzer with a wider measurement range, from extremely low to high luminance. With its new sensor circuits, the CA-410 achieves an accuracy-guaranteed luminance measurement range from 0.001 to 5,000 cd/m2.
