The impossible has been done!
Monocrystalline Diamond Spheres, Precision in Every Direction
Dutch Diamond Group has developed a specialised process for manufacturing highly accurate spheres from monocrystalline diamond. Diamond combines exceptional hardness, wear resistance, chemical stability, thermal conductivity and optical properties. By processing this material into precision spheres, we create components for demanding mechanical, metrological, scientific and optical applications. In addition to free standing diamond spheres, we can mount spheres onto shafts, stems and customer specific holders made from various technical materials.
Diamond spheres can also be processed into hemispheres and spherical optical components
Key Properties
- Exceptional wear-resistance
