With the SI-COLO-GD-40 made by Sensor Instruments there now is a sensor that allows the simultaneous and outside-light-independent detection of color and gloss value.
The color value x,y and the gray value INT are determined by way of the integrated RGB detector, the relationship of diffuse and direct reflection GN is determined by means of two photo-detectors that are arranged in such a way that one detector is positioned in the direct reflection, whereas the other detector receives a section of the diffusely scattered light. The sensor is able to store up to 31 references in the four-dimensional x,y,INT,GN space, and it provides various evaluation methods.
The color gloss sensor is excellently suited for applications involving automobile interior components where products with highly similar colors have to be inspected.
