Diamond Turned Optics

product summary

Cimcoop is utilizing some of the most modern 3-axis diamond turning equipment on the market today. Our ISO 9001:2015 certified facilities are strictly temperature and humidity controlled in order to deliver the highest accuracies possible, at or near the theoretical limits of the machine equipment. Geometries we produce include rotationally symmetric spheres, aspheres and diffractives from 1 to 200 mm. In addition, we are able to turn freeform shapes to manufacture non-rotationally symmetric surfaces. Measurements are done on a best-in-class 3D tactile system.
