High-quality quartz sand serves as the primary raw material in the production of optical glass. When combined with appropriate additives, it allows for the creation of advanced optical components. Rare earth elements are particularly valuable due to their high refractive index, low light dispersion, and excellent chemical stability. These properties make them ideal for manufacturing lenses used in high-end optical instruments such as cameras, camcorders, and telescopes. For instance, a bismuth-based glass containing 36% yttrium oxide (Y₂O₃) and 40% boron oxide (B₂O₃) exhibits exceptional optical performance and is essential in the production of precision lenses for modern cameras and periscopes. Additionally, certain rare earth elements possess radiation-shielding capabilities, making them useful in the development of protective glass for environments exposed to high levels of radiation. This versatility ensures that rare earths continue to play a crucial role in advancing optical technology across various industries.
