... approximation holds. But let痴 focus on the Gaussian beam for concreteness. The Gaussian beam stays Gaussian through any optical system as long as the paraxial approximation is valid. As soon as the paraxial approximation breaks down (i.e., nonlinear terms become important), the beam will become non- ...

... Index of Refraction The amount of refraction depends upon the difference between the speeds of light in the two media. The index of refraction for a material is the ratio of the speed of light in a vacuum to the speed of the light in the material. • A low index of refraction (near 1) causes light t ...

... Upon strong reflection off a layer a standing wave is formed which effectively changes the refractive index felt by the total field. If the Bragg peak is placed near Brewster’s angle, only the s-component feels this electric field modulation and change in refractive index which causes a phase shift ...

... The lens that was used for this lens design example was based upon the Sugawara design. It was chosen because it exhibits an aggressive f/number in image space (f/2.0), and was readily available. It is not necessarily the best form for this application, nor is this lens optimal in every way. It does ...

Harold Hopkins (physicist)

Harold Horace Hopkins FRS (1918–1994) was a renowned British physicist. His Wave Theory of Aberrations, (published by Oxford University Press 1950), is central to all modern optical design and provides the mathematical analysis which enables the use of computers to create the wealth of high quality lenses available today. In addition to his theoretical work, his many inventions are in daily use throughout the world. These include zoom lenses, coherent fibre-optics and more recently the rod-lens endoscopes which 'opened the door' to modern key-hole surgery. He was the recipient of many of the world's most prestigious awards and was twice nominated for a Nobel Prize. His citation on receiving the Rumford Medal from the Royal Society in 1984 stated: ""In recognition of his many contributions to the theory and design of optical instruments, especially of a wide variety of important new medical instruments which have made a major contribution to clinical diagnosis and surgery.""
