... In this example, the output NA will be 0.0022 or, since NA = Sin ß, where ß in the half angle in degrees, we get ß = 0.13 degrees. We may convert this to radians to get 2.2mRad divergence. Again, this represents the half angle. You will notice that since the output beam diameter is 100X the fiber di ...

... The  sign between kx and t determines the direction the wave travels along the x-axis. + wave travels to left (in the direction of decreasing x) - wave travels to right (in the direction of increasing x) The phase angle  shifts the cosine or sine function left or right. This can be used to match ...

... 4. Use Fermat’s principle to show that a thin lens with thickness given by w = w0 − αy 2 , where y is the distance from the axis, will focus paraxial rays from an object on the axis, and find the focal length as a function of α and the refractive index n. [Hint: the best way to interpret“paraxial” i ...

They are supposed to select a doublet lens of the proper focal length from a catalog such that for a typical source the lens is substantially illuminated. This in turn will illuminate a substantial part of the grating which will result in higher resolutio ...

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.""
