Aspheric Analysis
The Form Talysurf PGI 2540 is supplied with Taylor Hobson’s dedicated Aspheric
Analysis Software. This provides analysis of aspheres up to 20th order.
Key features of the software include:
• SAG table generation at user-defined x intervals
• Derived coefficients analysis
• Astigmatism analysis
• Base radius optimization
Asphero-diffractive Analysis (optional)
When combined with the results of the Aspheric Analysis software, the Diffractive
Analysis software allows the residual diffractive form to be analysed and the underlying
form error to be visualized. Numerical results include overall Pt, measured zone
height, zone height error and zone half-diameter.
Key features of the software include:
• Visualisation of form error after removal of diffractive design
• Clear indication of zone transitions
• Zone parameters can be exported to a CSV file for further analysis
• Designs can be saved and restored easily. |
