II-VI Incorporated develops, manufactures, and markets engineered materials, and optoelectronic components and devices worldwide. The company operates in three segments: II-VI Laser Solutions, II-VI Photonics, and II-VI Performance Products. The II-VI Laser Solutions segment offers optical and electro-optical components and materials primarily used in high-power CO2 lasers; fiber-delivered beam delivery systems, and processing tools and direct diode lasers for industrial lasers; direct diode laser modules, sub-systems, and systems; super-hard materials processing laser systems; and compound semiconductor epitaxial and gallium arsenide wafers. The II-VI Photonics segment provides crystal materials, optics, microchip lasers, and optoelectronic modules for use in optical communication networks and other consumer, life sciences, and commercial applications. It also offers pump lasers, optical isolators, and optical amplifiers and micro-optics for optical amplifiers for terrestrial and submarine applications within the optical communications market. The II-VI Performance Products segment provides infrared optical components and high-precision optical assemblies for military, medical, and commercial laser imaging applications; and silicon carbide engineered materials for thermoelectric devices and subsystems for silicon carbide applications. The company serves OEMs, laser end-users, system integrators of high-power lasers, manufacturers of equipment and devices for the industrial, optical communications, military, semiconductor, medical and life science markets, consumers, the U.S. government prime contractors, various U.S. government agencies, and thermoelectric integrators. It has strategic collaboration with Sumitomo Electric Device Innovations, Inc. to establish vertically integrated wafer fabrication platform. II-VI Incorporated was founded in 1971 and is headquartered in Saxonburg, Pennsylvania.
