What the toolkit includes

  • Editable Python 3.9+ source, English instructions and a self-test. Only the Python standard library is required.
  • Five example surfaces and 44 rows of reference CSV output, including base sag, polynomial departure, total sag and radial slope.
  • An optional ZPL macro and an original example lens. Total sag was cross-checked at 31 points on three surfaces in OpticStudio 18.9.0.

Surface model

Use signed vertex radius R in millimeters, conic constant k and unnormalized A₄, A₆, A₈ and A₁₀ terms. Compare the base conic, polynomial contribution and total sag. The sample and web preview use the same units.

Delivery and use

The digital product is an English-language ZIP for running calculations locally with Python. Its geometric model evaluates an ideal, rotationally symmetric surface at the specified radii. Review the input conventions before using results in an engineering decision.

A toolkit purchase licenses one individual or one named user, including a named user working for a company. That user may use and modify the scripts for their own internal optical engineering work. They may share resulting reports, charts and CSV output with clients. The source toolkit and modified copies may not be redistributed or resold. Applicable statutory rights are preserved.
