Form Accuracy Measurement of High Precision Aspheric Optics

A broad range of applications in the consumer, industrial, and defence arenas make use of Aspheric optics nowadays. Aspherics manufacturers depend on the metrology systems from Taylor Hobson for demanding applications.

The Single-Point Diamond Turning (SPDT) technique permits the rapid and efficient production of highly accurate aspheric optics. Form precision at sub-wavelength levels renders the metrology very critical to the production process. The Form Talysurf PGI Aspherics Measurement System from Taylor Hobson has become the gold standard for global optics users, by enabling form accuracies as low as 1/10.

Software for Aspherics Analysis

Taylor Hobson's excellent algorithm capability allows detailed analysis of aspheric optics. PGI Aspherics Systems are supplied with Surface Finish Parameters, Form Error, SAG Tables, Radius Optimisation, and Astigmatism Analysis features. An excellent Derived Coefficients module, which allows the direct calculation of aspheric data from the component, is also available with the software.
