4-inch Zygo interferometer
12-inch Goetz AutoCollimeter
18-inch Zygo Interferometer
32-inch Zygo Interferometer
  • The facility includes the classical testing and measuring techniques, such as the foucault and ronchi tests.

  • Surface figure measurement devices include, Zygo, Interferometers with 4, 18, and 32 inch beams, a laser unequal path interferometer (LUPI), Bauer scanning profilometer, continental long trace profilometer (LTP), cranfield 1 meter profilometer, tallysurf and tallystep profilometers, a grant microdensitometer for measuring interferograms, 1 meter collimator and a diffraction limited 16 inch goertz collimator.

  • Surface finish devices include: three wyko inferometric microscopes with 2D and 3D detectors, optical heterodyne profilometer, and two bidirectional reflection distribution function (BRDF) instruments (UV and visable sources).
