Reflectivity & Color

Reflection, like transmission, is a fundamental optical property of an object and a basic component of spectroscopic measurements. For different kinds of samples, the two basic modes of reflection and transmission evolve into more forms in order to obtain the best spectral measurement data. The two main types of reflection from the surface of an object are specular reflection and diffuse reflection. The reflection of light on a perfectly flat surface is specular reflection. The reflection of light on a rough surface is diffuse reflection. The reflection of light on the surface of most objects falls somewhere in between. Reflectance measurements can be used to measure the reflectance of a component, to measure the reflected color of an object and to measure the composition information in a chemical sample.

Color measurements, based on reflectance measurements, are furthered by a spectrometer to accurately measure SCI reflectance data of a sample. It can accurately measure and represent a various color difference formulas and color indices   in a variety of color spaces.
