PGI Optics Profilometers

Optical Profilometers for Surface Finish, Form Measurement in Optical Metrology

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 Form Talysurf  PGI Optics

(High performance & high accuracy Taylor Hobson 3D Non-contact Optical Measurement Systems are: LUPHOScan HD, LUPHOScan SD, LUPHOScan SL)
