Build the physics, then press the software hard. Focus on:

1. Foundations first: Wave optics, aberrations, radiometry, imaging metrics. A concise text like “Introduction to Modern Optics” (Fowles) keeps the math honest.

2. Sequential vs. non-sequential: Know when to switch. Imaging lenses and MTF in sequential; scatter, ghosting, and stray light in non-sequential.

3. Optimization craft: Merit functions with sensible operands and weights. Use constraints to avoid non-physical solutions. Blend global and local searches.

4. Tolerancing: Add realistic manufacturing and alignment errors. Link tolerances to image quality metrics you truly care about.

5. Materials and coatings: Keep glass catalogs current. Model coatings and polarization when they matter.

6. Automation: Script with ZPL or drive OpticStudio via MATLAB/Python to sweep parameters, run batches, and generate reports.

7. Validation: Rebuild classic designs to benchmark your approach. Compare to measured lab data whenever possible.

Consistent practice—small studies, then full systems—cements instincts.
