Fused Silica Optics
II-VI Infrared, the world leader in laser optics, introduces customized fused silica optics for direct diode and fiber or disk laser applications at powers greater than 1kW. Fused silica aspheres are designed to be diffraction limited and achieve smaller spot sizes than typical spherical lenses. For less sensitive applications, II-VI also manufactures fused silica spherical lenses for added convenience. The availability of fused silica debris shields, mirrors and mounted optics make II-VI Infrared the definitive source for any 1μm requirement. Whether for welding or cutting, II-VI offers low-absorbing, high quality lenses using industry-leading manufacturing resources and superior coating technology.
Replacement Focusing Lens Modules
II-VI Infrared presents its line of replacement focusing lens modules, created for fast and seamless exchanges. Using fused silica lenses, the focusing lens modules are designed for direct replacement in OEM cutting head models. Standard products are offered for 125mm, 150mm, 200mm and 250mm focal lengths with 28mm clear apertures. Custom designs are also available upon request.
Zinc Sulfide Multispectral Optics
II-VI Infrared also offers ZnS(Multispectral), zinc sulfide material treated by a hot isostatic press (HIP) process. Under intense heat and pressure, defects within the crystalline lattice are virtually eliminated, leaving a water-clear material with minimal scatter and high transmission characteristics. Freeform and aspheric surfaces, as well as standard spherical surfaces, on ZnS(MS) are made possible using II-VI Infrared’s industry-leading diamond-turning and manufacturing capabilities, along with progressive metrology. ZnS(MS) is an adaptable solution for advanced 1μm needs.
