WebThe RI of most gems is easily measured using a simple optical instrument known as a refractometer. Some gemstones are singly refractive; they have only one refractive … WebThus, knowledge of its optical properties is essential for many applications, in particular for remote sensing techniques. However, despite the fact that crystalline quartz has been an object of study for many years using various experimental approaches, its optical properties and in particular its complex refractive indices (CRI) remain uncertain.
