Lens arrays with a high numerical aperture and a filling factor of nearly 100%.

»Lensshape« free-form metrology 3D system

The »Lensshape« 3D system

The Fraunhofer IOF has developed the »Lensshape« system for the fully automatic, contactless and precise measurement of free forms. The 3D digitalizer works on the principle of self-calibrating structured light projection.

 

System parameters

  • Measuring range: up to ∅ 325 mm, height 100 mm
  • Measurement uncertainty: < 0.5 - 10 µm
  • Typical measuring time: 3 min
  • Number of views: 6 - 12
  • Tilt angle: up to 90°

 

The »UA3P« profilometer system

The Fraunhofer IOF has a tactile measuring “UA3P” profilometer from Panasonic.

 

System parameters

  • Measuring range: 200 mm x 200 mm x 45 mm
  • Measurement uncertainty: < 10 - 300 nm
  • Probe radius: 0.5 mm and 2 µm
  • Measuring force: 0.3 mN
  • Tilt angle: up to 60°
