How this tool works

A foundational ray-optics workbench organized around boundaries, imaging components, and multi-element systems.

Every graph or coordinate diagram displays units explicitly.

Core equations

n₁ sin θ₁ = n₂ sin θ₂1/f = 1/dₒ + 1/dᵢΦ = (nᵣ−1)[1/R₁−1/R₂+((nᵣ−1)d)/(nᵣR₁R₂)]

Assumptions

  • Paraxial thin-lens and mirror equations are used except for the thick lensmaker calculation.
  • Materials are homogeneous and isotropic.

Limitations

  • Aberrations, polarization, coatings, diffraction, and wavelength-dependent dispersion are outside these modules.
