Sapphire crystals exhibit good transparency in the 0.20~5.50μm wavelength range, with near-temperature-independent infrared transmission and high transmission rates for ultraviolet and visible light. As a result, they are commonly used to replace other optical materials in the production of optical component windows. Additionally, they are an excellent substrate material for the epitaxial growth of the third-generation semiconductor GaN, and their single crystal preparation process is well-established.

Our company, as a professional supplier of sapphire blanks, utilizes high-quality imported and domestic sapphire ingots to offer a variety of blanks in different specifications and sizes, including round, square, cylindrical, hexagonal, and custom shapes. These are used in watch lenses, optical components, instrument windows, bearings, and more.
