The CA-2500 2D Color Analyzer is ideal for the evaluation and inspection of a variety of display technologies, such as smartphones and tablet PCs.

This instrument uses XYZ filters that closely match the CIE 1931 color-matching functions to provide luminance and chromaticity measurements that have high correlation with the spectral response of the human eye.

The low-luminance measurement range has been improved from 0.1 cd/m squared to 0.05 cd/m2. It is compact and lightweight which makes it easy to be set up anywhere. The service life measurement cycles have been increased to approximately 5 times to that of the CA-2000, which makes it applicable for use in the production area.

The advanced Data Management Software, CA-S25w, included as a standard accessory, provides advanced functionality and simple operation to make the entire measurement process easier. From measurement preparations such as focusing and positioning, to measurements of luminance and chromaticity and the evaluation of measurement results, it greatly streamlines the entire measurement process.
