General Introduction: Schott Sapphire, as one of the hardest, most durable and scratch resistant materials, offers a broad transmission range from UV to mid infrared wavelengths (250 - 5000 nm). The material is able to withstand extreme environmental conditions and temperature changes. SCHOTT offers sapphire materials, Raytek offers the machining process in different supply forms, dimensions, and in customized processing stages.
