rIQ 3.0™Introducing rIQ™ 2.0. rIQ 3.0™ is designed to measure the refractive index of glass fragments. rIQ 3.0™ stands for Refractive Index Quantification (version 3.0) and is built based upon the thermo-optical methodology defined by ASTM E1967. As such, it is an automated system which measures the refractive index of microscopic glass fragments by monitoring the change in refractive index of calibrated oils as they are heated and cooled.
