Imaging colorimeter

SS-2000XImaging colorimeterColor difference detection is the process of measuring the color difference between two samples (standard sample and tested sample). Traditional color difference detection is observed by the naked eye, and this method of color difference detection is affected by the surrounding environment and the observer's own condition, resulting in inaccurate measurement results. With people's increasing demand for color, this manual detection method can no longer meet the needs of professional color detection. In order to achieve more accurate color management, people will use more professional instrumentsImaging typecolorimeter.

Imaging colorimeterCIEColorimetryStandardize color measurement standards,traditionCorresponding regulations have been made for the optical path structure of the instrument and the observation angle,D/8°、45/0°And observersviewcorner2°、10°The sensor has been usedYXZOptoelectronic sensors and spectral analysis. This can only test local color differences and hues. Dual color cloud spectrum commonly uses mature imaging techniques to analyze each pixel of product color difference.Imaging colorimeterIt is a high-precision color measurement device based on image sensing technology, which captures multi angle images of the object surface and analyzes themRGBOr spectral data, to achieve quantitative evaluation of color difference. Its core advantage lies in the ability to simultaneously obtain color information and surface texture features, making it suitable for complex samples or fast online detection scenarios.Imaging colorimeterThrough multi angle image fusion and spectral analysis techniques, dual quantification detection of color and texture has been achieved
