Sapphire is an exceptionally hard crystal, second only to diamond in hardness, making it an ideal choice for highly durable optical components. Known for its excellent transmission from ultraviolet to the near-infrared range and remarkable chemical resistance, sapphire is used in demanding environments where standard glass would fail. It is commonly utilized in high-pressure windows, substrates for semiconductors, and protective coverings for watches and sensors. We provide sapphire in various forms and thicknesses, ensuring high-quality solutions for precision applications.
