So far Geometrical Optics Reflection and refraction from planar and spherical interfaces Imaging condition in the paraxial approximation Apertures & stops Aberrations (violations of the imaging condition due to terms of order higher than paraxial or due to dispersion) Limits of validity of geometrical optics: features of interest are much bigger than the wavelength λ Problem: point objects/images are smaller than λ !!! So light focusing at a single point is an artifact of our approximations To understand light behavior at scales ~ λ we need to take into account the wave nature of light.
