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.
