Main Features

Sensor with XYZ filters provides high correlation with responsivity of the human eye.

The CA-2500 utilizes a sensor with XYZ filters to offer spectral response that correlates closely with the CIE 1931 color-matching functions, instead of the RGB color-separation filters used in digital cameras or color CCD cameras. This ensures luminance/chromaticity measurements that correlate well with visual evaluation.

High-resolution 1-million-pixel CCD
High resolution 1 million pixel CCD (980×980) enables accurate measurements of even small areas.

Interchangeable lenses for measurements of various objects

Standard, wide, and telephoto lenses (plus two macro rings for telephoto lenses) enable measurements of objects of various sizes by selecting the appropriate lens.
Individual lens calibration using multiple focal points
Each lens is individually calibrated at various focal points for the responsivity fluctuations caused by the instrument's sensors and optical filters and the lens itself. Accurate measurement of luminance distribution and chromaticity distribution can be started immediately after purchase.

Easy operation with included software

New developed, user-friendly software CA-S25w enables PC control of the CA-2500 for quick and efficient measurement, data analysis, and evaluation with easy operation. This combination is a powerful tool for development evaluation or inspection.

New subject setting assistance function

^{Measurement preparations are easier with focus adjustment section views and positioning assistance display}

Easy focussing

^{With the Focus assist function it is very easy to focus in real time! The sharp edge in the graph assist you to find the optimum focus condition.}

Multi-subject measurements possible

^{Individual evaluation of multiple subjects can be performed with a single measurement.}
