Ray optics is valid only for

WebWe define a ray as the path along which light energy is transmitted from one point to another in an optical system. The basic laws of geometrical optics are the law of reflection and … WebThe use of Gaussian optics is valid only if an optical system is centered relative to an optical axis and if the rays of interest have only very small angles relative to this axis. Therefore, spherical aberration, which causes a focus shift with changing pupil size, known in ophthalmol-ogy as night myopia, cannot be described with Gaussian optics.
