3D Freeform Optics Profilometer for Surface Finish & Form Measurement The Form Talysurf® PGI Freeform (Phase Grating Interferometer) is a versatile, high resolution 3D Freeform profilometer for high precision measurement. It performs surface finish and form analysis for freeform optics. A fully automated, fast and accurate system for freeform optics measurement. The Form Talysurf® PGI Freeform provides 3D raster/radial measurement and analysis of spheres, aspheres, diffractives and freeforms. Reduced measurement cycle time with fully automated routines and analysis including batch measurements for freeform surfaces. Versatile and easy to use •Gauge range up to 28 mm* •Resolution down to 0.8 nm •Slope up to 50° •Measurement accuracy from 100 nm (PV) The Form Talysurf® PGI Freeform can work with many of the latest equations used for definition of freeform surfaces such as Toric, Bi-conic, Anamorphic asphere, Ellipsoid, NURBS, Zernike, A-Cylinder and Cloud of points.
