The Microspectra 1 CoalPro™ Vitrinite Reflectance Measurement System is a microphotometer designed for the organic petrographic analysis using Standard Test Methodologies ISO 7404-5 and ASTM D2798. This microphotometer is configured to measure the reflectance from vitrinite coals & kerogens per these and other international protocols. However, it also has a very flexible design. The Microspectra 1™ was developed anticipating the next generation of test protocols as well as for fluorescence and micro-imaging.

In its basic configuration, bundled with Microspectra Vitrinite Reflectance Analysis™ software, the Microspectra 1 CoalPro™ vitrinite reflectance measurement system grades vitrinite coals using the ISO 7404 and ASTM D2798 standard test methods. However, the Microspectra 1™ can also be configured as a full microscope spectrophotometer to measure the full reflectance spectrum and the spectral fluorescence from coal, kerogen and other petrochemicals. Additionally, it can capture high resolution, full color images: all with the same instrument..

With no moving parts, the Microspectra 1 CoalPro™ is durable and user friendly. Designed with flexibility and speed in mind, the Microspectra 1 CoalPro™ Vitrinite Reflectance Measurement system rapidly measures vitrinite reflectivity and also has the ability to do other types of spectroscopic and petrographic analysis and imaging. With this flexibility of design, it will easily comply with future changes in coal testing methods and your own experiments.
