II-VI Infrared: Our History
In 1971, II-VI Incorporated began by exclusively producing the highest-quality materials available for manufacturing high-power industrial CO2 laser optics. Today, we have diversified into numerous business units for near-infrared optics, YAG components, and telecommunications components (VLOC); defense and aerospace optics (Exotic Electro-Optics); thermoelectric cooling devices (Marlow Industries); radiation detection products (eV PRODUCTS); silicon carbide (II-VI WBG); and advanced materials development (II-VI AMDC).
As II-VI Incorporated continues to grow, we focus on the company’s original, industry-leading products: infrared and CO2 laser optics and materials. And thanks to decades of innovation in ZnSe materials processing, thin-film coating, precision diamond-turning, and finished optics fabrication, II-VI Infrared is the world leader in CO2 laser optics. From developing original equipment optics for the world’s top laser manufacturers, to producing replacement laser optics for end users, our company delivers an unbeatable combination of innovation, quality, and experience. II-VI Infrared also delivers the largest vertically integrated CO2 laser optics manufacturing process -- from raw materials to finished coated products -- in the world.
II-VI Infrared’s products range from replacement CO2 laser optics and nozzles to lenses, partial reflectors, windows, beamsplitters, mirrors, beam expanders, reflective phase retarders, scanning-laser system optics, diamond-turned custom optics, and more. Our products and reputation make us the number-one supplier to original equipment manufacturers of CO2 laser systems worldwide, while our capabilities are without rival in the industry.
Our diamond-turning facility is among the largest and most advanced in the world, offering services such as flycutting and multiple-axis turning, as well as fast and slow tool servos for custom optics. Single-point diamond-turning is used in finishing transmissive optics and mirrors in a variety of metals and IR materials.
Major investments in computer design programs, evaporation equipment, clean rooms, and testing facilities enable us to offer a broad range of IR thin-film coatings. II-VI Infrared is known for designing and producing consistently low-absorption coatings for high-power CO2 laser optics. Additionally, our talented and experienced engineering team, using optical design software and CAD systems, designs and builds standard and custom optics as well as specialized mounts, components, and electro-optic assemblies.
Our quality assurance program includes comprehensive testing, documentation, and statistical analysis to ensure that each optic and component performs to customer requirements.
