II-VI Infrared is the world's leading manufacturer of high-power CO2 laser lenses, and the preferred optics supplier of CO2 laser OEMs worldwide.
Our line of lenses includes:
THE BEST ... NOW EVEN BETTER. II-VI Infrared's MP-5 is an ultra-low absorbing lens that ships directly from the factory as a standard OEM CO2 laser component. Its superior features include a patented coating design enabling lower thermal distortion, visible transmission for reduced set-up time, and easy detection of thermally induced stress. The MP-5 is backed by over a decade of proven performance, and this ultra-low absorbing lens is designed, produced, and supported by II-VI Infrared, the world leader in CO2 laser optics. A specially coated zinc selenide (ZnSe) focusing lens, the MP-5 is available in both 1.5" and 2.0" diameters, and ships in 14 standard replacement lens configurations for most popular OEM laser models.
Meniscus lenses are designed to minimize spherical aberration producing a minimum focal spot size for incoming collimated light. In addition to the standard focal lengths listed below, II-VI maintains an extensive inventory of test plates and tooling, resulting in no additional tooling charges for focal length fabrication. Besides the plano-convex, meniscus, and aspheric lens shapes offered in this catalog, II-VI routinely fabricates biconvex and negative focal length lenses upon request. Our in-house optical engineers can design the component or optical system which provides the exact performance you require. Please contact our sales and engineering staff for a quotation.
Plano-convex lenses, the most economical transmissive focusing elements available, are ideally suited for laser heat treating, welding, cutting, and infrared radiation collection where spot size or image quality is not critical. They are also the economical choice in high f-number, diffraction limited systems where lens shape has virtually no effect on system performance.
For proper performance with a plano-convex lens, the curved surface should face toward the incoming collimated beam or the longer conjugate distance (the object and image distances together are referred to as the conjugate distance).
In addition to the standard focal lengths listed here, II-VI maintains an extensive inventory of test plates and tooling. This enables fabrication of many other focal lengths without additional tooling charges.

II-VI Infrared, the world leader in CO2 laser optics, is now providing replacement Trumpf Cut Lenses. These lenses, used in Trumpf's latest-generation single cutting head TruLaser machines, feature a contoured flat on one edge. This planar surface works with Trumpf's LensLine monitoring system, which monitors contamination on the Cut Lens. By providing this feedback, the system enables the laser operator to know the status of the Cut Lens, including when it needs cleaned or replaced, and also to avoid any unnecessary lens cleaning work and laser downtime.
Trumpf Cut Lenses also provide the laser operator with another advantage. Because of its unique geometry, Trumpf's Cut Lenses can only be positioned in one way, assuring that the lens and its holder are always in perfect alignment. This eliminates the need for time-consuming beam centering each time the Cut Lens is removed and re-installed.
II-VI Infrared provides these replacement Cut Lenses using patented technology licensed from Trumpf (US patent #7,875,830; China patent #100,533,193C; Europe patent #1,800,156).
CO2 Laser Consumables: OEM-spec optics, nozzles, and accessories From rear mirrors to focusing lenses, and every optic in between, II-VI Infrared offers replacement laser optics and components, including focusing lenses and focusing (parabolic) mirrors, bend mirrors, collimators, reflective phase retarders, rear mirrors, output couplers, and output windows. Our replacement laser optics are made from II-VI's own zinc selenide (ZnSe), as well as copper (Cu), gallium arsenide (GaAs), germanium (Ge), molybdenum (Mo), and silicon (Si). II-VI Infrared's world-class thin-film coatings are applied to enhance optical properties, while our quality assurance program includes comprehensive testing, documentation, and statistical analysis to ensure that each optic and component performs to customer requirements. For additional information, contact a II-VI Infrared sales and support representative. In addition to optics and optical components, we also offer a comprehensive line of over 750 replacement laser nozzles and accessories, all in stock and built to major OEM specifications.
