PGI Optics Profilometers

Surface Finish & Form Measurement Optical Profilometers

Taylor Hobson’s Form Talysurf PGI optical measuring instruments are stylus optical profilometers, it delivers surface finish and form measurement of plastic lenses, spheres, aspheres, freeforms, IR glass & crystals and diffractives up to 300 mm in diameter. Our patented PGI (Phase Grating Interferometer) technology enables you to measure large sags with short length styli for the highest accuracy measurements. We designed PGI optical profilometers with powerful aspheric analysis software tools to improve your capacity and capability. 

High performance Taylor Hobson Contact Optical Measurement Instruments are:  Form Talysurf  PGI Freeform, Form Talysurf  PGI Matrix and F orm Talysurf  PGI Optics

Form Talysurf PGI Freeform
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

Form Talysurf PGI Matrix
The Form Talysurf PGI Matrix is the perfect all-around optical profilometer/instrument for fully automated 2D and 3D form metrology of optics ranging from small, mobile phone lenses to large astronomy optics.
Our productivity tool kit, offers a unique advantage for batch testing when measurement speed and throughput is a must.
The integrated PGI gage technology coupled with sophisticated automation software and hardware now offer users the ability to measure freeform optics that were never before possible.

  • • Reduced costs and improved manufacturing yields 

  • • Improved utilisation 

  • • Improve your competitiveness 

  • • Future metrology savings 

Form Talysurf PGI Optics
Following its first release in 1984, the Form Talysurf quickly became the number one tool for optics manufactures in measuring aspheric form error. Since then, we have installed thousands across the globe becoming a true industry standard.

Our patented PGI (Phase Grating Interferometer) technology enables you to measure large sags with short length styli. This enables us to combine very high stiffness and low force offering much greater accuracy and repeatability than our competitors.

The Form Talysurf PGI Optics offers premium optics metrology packages designed to optimise performance and enhance your manufacturing capability. We offer a large range of instrument sizes and software packages to optimise your measurement needs as well as your budget
