CNC grinding of spherical surfaces

Cimcoop uses state-of-the art 5-axis CNC equipment to grind spherical surfaces on Silicon and optical glass. We deliver large quantities of Silicon pre-generated lenses that are used for demanding thermal imaging applications. The remaining portion of the lenses we grind continues further to be delivered as complete single lenses or achromats.
