Form Talysurf PGI 840 PRODUCT Precision form & surface finish measurement for aspheric optics At Taylor Hobson we are proud of our reputation as the solution provider of choice within aspherics metrology. The Form Talysurf has evolved over the past 20 years, delivering continuous improvement for our customers. The PGI 840 Aspherics Measurement System represents a new level of performance for applications such as: •Diamond-turned or Ultra-precision ground molds for plastic or glass optics •Aspherics for laser applications •Digital cameras, projectors, etc •IR & Diffractive optics up to 120mm diameter The Form Talysurf PGI 840 from Taylor Hobson is a premium specification measurement system for the small to medium sized aspheric optics market. It is designed for applications where optimum component quality and consistency cannot be compromized. Ultra-high precision processes such as Single-Point Diamond Turning allow aspheric lenses to be manufactured with form tolerances down to small fractions of ë. To achieve such levels of precision, metrology must be fully integrated with machining. Form Talysurf PGI 840 delivers this capability by directly exporting measurement results back to the machine tool, creating a corrective 'feedback loop'. New custom styli expand the range of applications which can be measured using the PGI 840. For more details of the Form Talysurf PGI 840, please contact your local Taylor Hobson sales agent, or go to our website. The Form Talysurf PGI 840 has been developed specifically for the optics industry. Every aspect of manufacture is to the highest possible level which results in unparalleled system performance. •120mm Traverse unit with 0.25ìm \ 120mm straightness •8mm Gauge range, 0.8nm vertical resolution •16mm Gauge range possible with 120mm stylus arm •2nm RMS noise floor provides market-leading optics surface finish measurement capability •Extensiv e Range of Optional Accessories, including styli for demanding applications PGI 840 - A new generation of excellence PGI 840 has industry leading specifications Taylor Hobson's recently launched Aspherics Analysis Software incorporates a number of new features expressly designed to meet the needs of Aspherics Optics Manufacturers, including: •Aspheric Form Analysis •User Selectable Radius Optimisation and ës Filter •Report Generation Capability •SA G Tables •As tigmatism Analysis •Deriv ed Coefficients Module (optional) •Aspher o-Diffractive Analysis (optional) Aspherics Analysis Software Designed to meet research & production needs
