AR Waveguide TIR / FOV Calculator

Compute total-internal-reflection envelope, angular bandwidth of an in-coupling grating, and resulting field-of-view for a planar optical waveguide.

Model planar waveguide optics for AR/VR displays. Compute TIR critical angle, grating in-coupling conditions, and achievable field-of-view as a function of core index, cladding index, grating period, and wavelength. Includes chromatic FOV analysis and design recommendations.
