Visit Taylor Hobson at the BI-MU Show, Milan

See the PGI 840 Aspheric Measurement System - A premium specification measurement system for small to medium sized aspheric optics.

05-oct-2010 till 09-oct-2010

Venue: Fiera Milano, Milan, Italy

The 27th BI-MU is the most prominent event that offers a broad variety of effective technological solutions for the whole manufacturing industry including metal forming and metal cutting machines, robots, automation and auxiliary technologies. The trade show will also comprise a high-tech conference program, specifically designed for the associated young people to focus on professional opportunities for them in the relevant sector.

Talysurf CCI Lite - non contact 3D Profiler

The Talysurf CCI Lite is an advanced type of measurement interferometer (a non contact 3D Profiler). It uses an innovative, patented correlation algorithm to find the coherence peak and phase position of an interference pattern produced by our precision optical scanning unit.

Flexibility

The Talysurf CCI Lite is invaluable for many applications requiring high precision 3D profile analysis. A variety of objectives are available and can be fitted simultaneously to the turret, enabling many types of surface to be measured. A fully automated stage and auto measurement routines add to the high level of flexibility.

Surfaces are quantified absolutely using the latest internationally recognized parameters for both 3D and 2D surface characterization.

Form Talysurf PGI 2540

Form Talysurf PGI 840

Ultra-high precision processes such as Single-Point Diamond Turning allow aspheric lenses to be manufactured with form tolerances down to small fractions of, reducing wavefront aberations to insignificant levels.

To achieve such levels of precision, metrology must be fully integrated with machining. The 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 measured using the PGI 840.
