Summary
Summary
The NSRA operand may be used together with a Source Ray to calculate the surface sag of an object in non-sequential ZEMAX. This can be done by either:
• Using the Universal Plot 2D analysis feature
• Using a ZPL macro
In either case, the step size of the calculations can be explicitly specified, allowing for arbitrary resolution of the surface sag.

This seems unnecessarily
R=N h=NPAR(1,3,1) x1=1+sqrt(1-h*h/R*R) x sag=(h*h)/(R*(1+sq |
