The CoalPro II microscope photometer from Craic Technologies Inc. performs optical analysis of vitrinite and other macerals commonly found in coal, kerogen and source rock. The instrument is designed to determine the energy grade of these potential power sources rapidly and accurately and is employed to ensure that the materials used in energy generation are optimal. The CoalPro measures the amount of light reflected from samples of the coal blend at hundreds of points, after which a statistical analysis is done by its software. The results determine the amount of vitrinite in the sample, the sample’s thermal maturity and, therefore, its energy content. Previously, hundreds of sample measurements were required. The CoalPro is sensitive to fluorescence and enables the collection of full-color images.

The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
optical analysis
The mathematical evaluation of an optical system to determine and quantify its basic optical properties and image quality characteristics.
