Question 2
I am entering aspheric terms in the Insert Lens Element dialog, how are the parameters defined in the sag equation?
Synopsis
Aspheric Terms - Insert Lens dialog
Solution
The description of the terms in the sag equation is in the User's Manual (Lens Element section in Chapter 2) and Help (Geometry Commands > Lens Element > Surfaces). The variables in the Insert Lens Element dialog are defined as follows:
- Curvature = 1/Radius
- Aspheric surface equation - each aspheric surface type lists terms that are explained in the Help and User's Manual.
