CA-2500 2D COLOR ANALYZER
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.

2D色彩分析儀CA-2500使用XYZ濾鏡（該濾鏡具備與CIE 1931等色函數非常接近的光譜靈敏度），與數位攝像機等設備中所使用的RGB分色濾鏡相比，能夠測量與人眼感光度相近的亮度和色度。
標配具有良好操作性的新軟件CA-S25w
該軟件具有輔助對焦、輔助對位、自動檢測的功能，用戶無需進行繁瑣的測量準備工作。
標配SDK（Software Development Kit）
二維色彩分析儀CA-2500配備可用於用戶軟件開發的SDK，藉此可高效製作自主開發的獨創軟件。
