How do I add aspheric terms to a surface in OSLO?
Adding terms to an aspheric surface
- Identify the surface that you want to add an aspheric to and choose the grey box in the “Special” column of that surface.
- Choose ” Polynomial Asphere (A)” from the pop-up list
- If you want to add a conic constant to the surface choose ” Conic/Toric” from the resulting pop-up list
- If you want to add higher order aspheric terms to the surface, choosing ” Standard Asphere” will allow you to enter a sufficient number of higher order aspheric terms for most purposes. (Note that other forms of aspheric surfaces are available)
Refer to the online help (Contents>>Lens Entry>> Special Surface Data>>Aspheric) for a description of the mathematical formulas of the different aspheres.
