Non-contact Spectrocolorimeter SELECTION GUIDE SENSORS Introducing Colorimetry Color only exists through the combinaton of three elements: a light source, an object and an observer. Color becomes a subjectve sensaton, which can be described with a color name. The Internatonal Commission on Illuminaton defined some standards allowing us to quantfy colors. In consequence, colorimetric spaces are defined for different pairs of illuminant/observer and the color is identfied by three coordinates, for example CIELAB, CIELUV… Two categories of instrument are used for characterizing the color of an object: the colorimeters and the spectrocolorimeters. A colorimeter is a very simple system proposing a series of colored filters in order to simulate the normalized curves of a standard observer. The measurement is not very accurate and it does not allow users to detect differences that are invisible for some illuminants and visible for others (metameric colors). In contrast, a spectrocolorimeter includes a dispersive component (gratng, prism) allowing the measurement of the light reflected by the object in a much more precise manner, for the whole range of visible wavelengths. RUBY spectrocolorimeter RUBY is a perfect soluton for real tme measurement of color. The fast detecton of color drifts and servo-controlling producton tools possibilites allow a cost reducton for a low level of investment. 3D SYSTEMS SPECTRO COLORIMETERS • High acquisiton speed, • Non contact measurement, • Synchronizaton with custom machines, • Stand-alone use. In additon to color monitoring, different kinds of applicaton are available: Whiteness measurement, formulaton, counter-typing, characterizaton of the effects of materials and light stability measurement (artficial or natural ageing). Applications Spectroscopic and colorimetric measurements are used for analyzing: Reflectance of diffusing materials and samples, Intensity and color of light sources and displays, transmittance of filters and liquids.
