rIQ™ 3.0 Glass Refractive Index Measurement
rIQ™ 3.0 (Refractive Index Quantification) is the ultimate solution for precise and automated glass refractive index measurements in forensic and materials science applications. Based on ASTM E1967 and SWGMAT standards, this advanced system employs thermo-optical methodology to measure the refractive index of microscopic glass fragments with high accuracy and reproducibility. The system automatically tracks refractive index changes in calibrated immersion oils during controlled heating and cooling cycles, ensuring reliable, repeatable results for quality control, forensic analysis, and research purposes. rIQ™ 3.0 offers seamless integration with CRAIC microspectrometers, expanding its capabilities to include transmission, fluorescence, and color spectra analysis of glass fragments.
