Sapphire crystal (Al2O3) is an excellent substrate for a range of rugged applications. It has high transmission from 150nm up to around 5µm therefore ideal for UV, Visible and IR applications. Sapphire lenses have excellent mechanical strength and hardness. With sapphire having superb thermal and chemical resistance and being scratch resistant, sapphire is a perfect choice for lens applications . Sapphire is inert and resistant to attack from most processing environments, such as hydrofluoric acid. VY supply a range of sapphire components, such as sapphire lens, sapphire flat, sapphire window, sapphire dome, sapphire ball lens, sapphire prism, sapphire rod, sapphire tube, etc. Our sapphire lens can also be antireflective coated to increase efficiency in UV and IR applications.
