Have a rainbow of applications

Dr. Aaron Gage and Dr. Andrew Tatsch, Ocean Optics Inc.

Color analysis is a powerful detection tool. Its ability to ferret out information about the absorbance and reflectance properties of a material makes it ideal for identifying a range of characteristics. Applications surround us, from paint-matching systems at hardware stores to scientific methods for studying how birds react to the colors of plumage. The level of detail and the quality of data required in color analysis systems vary according to complexity of the application, which can be as simple as a color imager or as sophisticated as a laboratory-grade spectrometer.

    absorbance
    The natural log of the ratio of absorbed intensity over the total intensity which gives a constant value assuming a stable volume as well as energy. In optical physics the absorbance may be defined as the absorption cross section multiplied by the absorbing material length.
