Form Talysurf PGI Optics

Optics Surface Finish & Form Measurement Equipment

The Form Talysurf PGI OPtics contact stylus optical profilometer, measures surface finish & form of Optical components, from a large diameter lens with large SAG to small low SAG plastic lenses. It capable of measuring both IR (infra red) and visible substrates. It is capable of high accuracy measurements on spherical, diffractive, fresnel and aspheric lenses up to 300mm diameter as well as more complex surfaces such as cylinders and freeforms. Mirror optics can also be measured. These capabilities make it the goto instrument for optical manufacturers.

    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
