Since its release in 1984, the Form Talysurf has quickly become the go-to gauge for optical manufacturers to measure aspherical form errors. Since then, the instrument has been used by thousands of manufacturers around the world, making it quickly become a good measurement standard in the industry.
The technology-enabled PGI (Phase Grating Interferometer) is capable of measuring large sags using short stylus. It combines high stiffness and low force to provide higher accuracy and repeatable measurement capability than our competitors.
The PGI Optics series offers a unique optical metrology software package that can achieve the best performance of optical lenses and increase production capacity. We are able to offer a wide range of instrument and software options to meet your technical and budgetary needs.
