II-VI Incorporated offers ultra-precision diamond machining capabilities including both fly cutting and two-axis lathes. Our diamond turning division is supported by crystalline materials growth, optical fabrication, thin film coating and assembly facilities. Being a vertically integrated company enables II-VI to provide consistent quality and on-time delivery by having complete control over the entire manufacturing process. Our employees are dedicated to continuous process and product improvement which has made II-VI Incorporated a world leader in laser optics since 1971.

Diamond Flycutting

The Diamond Flycutting process is used to machine plano mirror surfaces in materials that are not easily polished. II-VI specializes in machinery copper mirrors for the CO2 Laser Market with surface finishes of less than 50 angstroms RMS and figure accuracies better than 1/4 wave P-V@632 nm. In addition to these copper products II-VI machines custom aluminum mirrors for industrial, medical, military and aerospace applications

2 Axis Machines

The versatility of 2 Axis Diamond Turning Machines enable them to machine an extensive range of materials and geometries. At II-VI we machine aspheric IR lenses in Ce, ZnS, ZnSe and Si materials as well as manufacturing spherical and aspheric mirrors in Cu, Al and/or Ni. This work is primarily done on a Nanoform 600 machine which, with its 24" capacity and 1.25 nm position resolution, represents the state-of-the-art for Diamond Turning. (The Nanoform is capable of machining surface finishes with 25Å RMS and figure accuracies of 1/8 wave P-V at 632 nm.) A second 2-axis machine specializes in small (<4"Ø) on axis components and this machine is more limited in its applications but generates Nanoform quality finishes on production quantities of components.
