API Reference

DeepLens exposes a small, composable API. Every optical system is a lens model that shares the common Lens interface — psf(), render(), optimization, and file I/O — and is built on optical surfaces, light/wave representations, and image-simulation utilities.

Pick the lens model that matches your optical system:

• GeoLens

  ---

  Multi-element refractive lens via differentiable geometric ray tracing. The primary model.

  GeoLens

• HybridLens

  ---

  Refractive lens plus a diffractive element — hybrid ray-then-wave propagation to the sensor.

  HybridLens

• DiffractiveLens

  ---

  Pure wave-optics lens built from diffractive surfaces and scalar diffraction.

  DiffractiveLens

• PSFNetLens

  ---

  Neural surrogate wrapping a GeoLens with an MLP for fast, differentiable PSFs.

  PSFNetLens

• DefocusLens

  ---

  Thin-lens / circle-of-confusion model for fast depth-of-field and bokeh.

  DefocusLens

Shared building blocks live in Optics Core; neural PSF predictors live in Surrogate Networks.
