Based on the proven NANOMEFOS technology DUI now brings the NMF600S. A machine specifically designed to provide easy and accurate metrology of complex optics to the workshop floor. This fast, non-contact tool is capable of measuring optics ranging from convex to concave and from flat to freeform, up to 600 mm diameter, with a typical measurement uncertainty below 15 nm RMS.

Compared to the TNO prototype it has been improved on many aspects. The footprint has been reduced to only 1.2 x 1.7 m (including the electronics). The robustness of machine has been improved, the probe has been optimized, the electronics has been industrialised and all software has been upgraded.


Versatile, no setup changes for measuring a broad range of surface shapes

  • Flat – Convex -Concave
  • Sphere – Asphere – Freeform
  • Off-axis

Large measurement volume of Ø600 x 125 mm

  • Ø420 mm for 45° convex
  • Unlimited asphere departure
  • Up to 5 mm PV and ±5° for freeform
  • Circular & non-circular surfaces

Footprint of 1.2 x 1.7 m

High point density to show mid-spatial frequencies

  • Full surface 1M points typical
  • Line scans with micrometer point spacing

Measurement uncertainty generally much smaller than 15 nm rms for all flats, spheres and aspheres; worst case freeform smaller than 30 nm rms.
