Offering the best of both Sophisticated solutions with

The industries of space exploration and lithography demand higher requierments for their instruments every year. TNO can offer you sophisticated solutions and experiments to safeguard your position. Our flexible in-house approach allows TNO’s experienced operators, optical designers and integrators to facilitate the experimental development of specially designed components such as freeform optics.

Research and manufacturing and . Our optical manufacturing experts Offering you the best of both, TNO is the focus on experimental research and the perfect partner for CNC Diamond Turning manufacturing of spherical, aspherical and and CNC Precision grinding of spherical, freeform optics. In addition we can also aspherical and freeform optics on non-ferrous assemble instruments for you. (e.g. ), crystals, polymers We focus on experimental research and the manu- facturing of spherical, aspherical and freeform optics

Diamond turning TNO’s ultra precise diamond turning lathes are able to machine both spherical, aspherical and freeform optical components into non-ferrous metals, crystals, polymers and glass using . In addition, the grinder produces spherical and aspherical components into glass, and ceramics.
