	II-VI Incorporated develops, refines, manufactures, and markets engineered materials and opto-electronic components and products worldwide. It operates through four segments: Infrared Optics, Near-Infrared Optics, Military &amp; Materials, and Advanced Products Group. The company provides precision infrared opto-electronic components, such as lenses, output couplers, windows, mirrors, and scan-lenses for use in CO2 lasers; and one-micron laser components, including modular laser processing heads, yttrium aluminum garnet (YAG) lasers, and other one-micron laser systems, as well as fiber optic cables and modular beam systems. It offers near-infrared optics comprising wave-plates, polarizers, lenses, prisms, and mirrors for visible and near-infrared applications; specialty coated glass wafers; coated windows; fiber and micro optics, optical components, and photonic crystal parts for optical communications; optical and photonic crystal parts for instrumentation and laser applications; and diode pumped solid-state laser devices for optical instruments, display, and biotechnology. The company provides optics and optical subassemblies for ultra-violet (UV) and infrared systems, including missile domes, electro-optical windows and subassemblies, imaging lenses, UV filter assemblies, laser cavity optics, and prisms and other optical components, as well as calcium and barium fluoride, YAG, and fused silica. It offers material processing and refinement products comprising rare earth materials; single-stage, micro, multi-stage, and planar multi-stage thermoelectric modules; extended life thermo-cyclers, thermoelectric thermal reference sources, power generators, and thermoelectric assemblies, as well as silicon carbide substrates, and metal matrix composites and reaction bonded ceramics. The company markets its products through a direct sales force, representatives, and distributors. II-VI Incorporated was founded in 1971 and is headquartered in Saxonburg, Pennsylvania.
