Chapter 4: Optical systems & ray tracing

This chapter collects OghmaNano’s optical system and ray-tracing tutorials for modelling 3D light propagation through lenses, apertures, and structured surfaces, and for measuring spatially and spectrally resolved light using detectors. The pages below are organised as practical, runnable tutorials that build from basic optical editors to full system-level ray-tracing analyses.

• 🧰 4.1 Optical system editors
  • 4.1.1 Light sources
  • 4.1.2 Optical detectors
  • 4.1.3 S-plane editor
• 📷 4.2 Lenses & optical systems
  • 4.2.1 Cooke triplet
  • 4.2.2 A modern long-focal-length (200 mm) prime prime lens
  • 4.2.3 A fun tour of the ray tracing features
• ✨ 4.3 Light interacting with films/surfaces
  • 4.3.1 Light reflecting from an AFM image
  • 4.3.2 Light escaping from a rough film
