: Since this is for visible light, Alex picks the "F, d, C" presets (blue, green, and red).
The MTF at the edge field collapses. Alex opens the manual → Chapter “Merit Function Operands” → finds MFCN (Merit Function Control Number) and MTFA (MTF at Frequency) . Adds operands to push MTF at 100 lp/mm above 0.3. Zemax Opticstudio User Manual--------

Start typing in the LDE. The feature is critical here. Adds operands to push MTF at 100 lp/mm above 0
By treating the with the respect it deserves, you will move from pressing buttons blindly to understanding the fundamental physics of light. And that is the true goal of optical engineering.
: Alex enters a "guess" radius of 100 mm and a thickness of 5 mm.
