In a medium of constant refractive index, n, the OPL for a path of geometrical length s is just If the refractive index varies along the path, the OPL is given by a line integral where n is the local refractive index as a function of distance along the path C. An electromagnetic wave propagating along a path C has the phase shift over C as if it was propagating a path in a vacuum, length of which, is equal to the optical path length of C. Thus, if a Webif a sufficiently strong convex lens is also placed in the light path. For two thin lenses in contact (focal lengths ƒ1 and ƒ2), the focal length ƒ of the combination is given by: 1 ƒ = …
