Subscripts 1 and 2 refer to initial and final optical media respectively. These ratios are sometimes also used, following simply from other definitions of refractive index, wave phase velocity, and the luminal speed equation:
An optical imaging system (gray box) that obeys the sine condition has a fixed ratio between the sines of the ray angles at the entrance and exit of the system, sin(α o) / sin(α i), that equals the magnification M. Using the framework of Fourier optics, we may easily explain the
In optics, a conjugate plane or conjugate focal plane of a given plane P, is the plane P′ such that points on P are imaged on P′. [1] If an object is moved to the point occupied by its image, then the moved object's new image will appear at the point where the object originated. In other words, the object and its image are interchangeable.
Principles of Optics, colloquially known as Born and Wolf, is an optics textbook written by Max Born and Emil Wolf that was initially published in 1959 by Pergamon Press. [1] After going through six editions with Pergamon Press, the book was transferred to Cambridge University Press who issued an expanded seventh edition in 1999. [ 2 ]
In optics, surface vertices are the points where each optical surface crosses the optical axis. They are important primarily because they are physically measurable parameters for the optical element positions, and so the positions of the cardinal points of the optical system must be known with respect to the surface vertices to describe the system.
This holds whether or not the numbers are integers; there is a formula (see here) that generates all integer cases. [ 5 ] [ 6 ] Second, also in a right triangle the sum of the squared reciprocal of the side of one of the two inscribed squares and the squared reciprocal of the hypotenuse equals the squared reciprocal of the side of the other ...

Economies of scope are "efficiencies formed by variety, not volume" (the latter concept is "economies of scale"). [1] In the field of economics , "economies" is synonymous with cost savings and "scope" is synonymous with broadening production/services through diversified products.
