Form Talysurf PGI Freeform
3D Freeform Optics Profilometer for Surface Finish & Form Measurement

Taylor Hobson’s Form Talysurf PGI (Phase Grating Interferometer) is a versatile, high resolution 3D Freeform profilometer for high precision freeform optics measurement. It performs surface finish and form analysis for freefrom optics.

The new Form Talysurf® PGI Freeform is a versatile, high resolution system dedicated to the measurement of high precision freeform optics. Providing 3D raster / radial measurement and analysis of:
• Spheres • Diffractives
• Aspheres • Freeforms

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

• Cloud of points

Measurement integrity and reproducibility

Taylor Hobson’s Form Talysurf® PGI Freeform is underpinned by decades of measurement experience, ultra-precision manufacturing expertise and FEA optimized design. These provide low noise and near flawless mechanical execution of the measuring axes.
