  • Optical Properties of Minerals

    The optical properties of minerals refer to their behavior in the presence of light and how they interact with light when observed using various optical techniques. These properties include transparency/opacity, color, luster, refractive index (RI), pleochroism, birefringence, dispersion, extinction, and crystallography.
