What is a Color Spectrophotometer?
A color spectrophotometer is an instrument designed for physical sample analysis via full spectrum color measurement. By providing wavelength-by-wavelength spectral analysis of a sample’s reflectance, absorbance, or transmittance properties, it produces precise data beyond that observable by the human eye. If desired, spectrophotometers can be used to calculate psychophysical colorimetric information as well.
Using Color Spectrophotometers
Color spectrophotometers offer a higher level of flexibility and versatility than colorimeters due in part to the fact that they offer multiple illuminant/observer combinations and can operate in multiple geometric arrangements, including 45°/0° and d/8°. As such, spectrophotometers are capable of measuring metamerism, identifying colorant strength, analyzing a comprehensive range of sample types, and giving users a choice between including or excluding specular reflectance to account for geometric attributes. Full-spectrum analysis also provides for greater specificity, potentially identifying color differences missed by colorimeters. Spectrophotometric equipment are ideally suited for a broad range of applications in the research and development phase, including color formulation and color system development, as well as color quality control throughout production.
