Using solves

Solves are a means of simplifying description of the lens system and of accelerating the optimization process. Simply put, a solve enables a surface to dynamically update depending on the paraxial properties of the system. Note that solves are implemented during the paraxial setup, before any real rays are traced. Solves are "forward only" in the sense that no solve can change things so that previous solves must be re-evaluated.

Curvature solves

Thickness solves

Semidiameter solves

Parameter solves

Glass solves

The glass solve popup menu on the surface data editor allows you to quickly change the glass to air, mirror, a model glass, or to set up a pickup from any previous surface.
