Refractive index — Refraction of light at the interface between two media. In optics the refractive index or index of refraction of a substance or medium is a measure of the speed of light in that medium. It is expressed as a ratio of the speed of light in vacuum… … Wikipedia
Gradient-index optics — is the branch of optics covering optical effects produced by a gradual variation of the refractive index of a material. An example of gradient index optics is the common mirage of a pool of water appearing on a road on a hot day. The pool is… … Wikipedia
Index of optics articles — Optics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.[1] Optics usually describes the behavior of visible,… … Wikipedia
Graded-index fiber — In fiber optics, a graded index or gradient index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the fiber axis (the imaginary central axis running down the length of the… … Wikipedia
Anti-reflective coating — Many coatings consist of transparent thin film structures with alternating layers of contrasting refractive index. Layer thicknesses are chosen to produce destructive interference in the beams reflected from the interfaces, and constructive… … Wikipedia
Digital planar holography — Planar waveguide Digital Planar Holography (DPH) is a new technology, developed recently, circa 2003, for fabricating miniature components for integrated optics. The essence of the DPH technology is embedding digital holograms, calculated in a… … Wikipedia
Photothermal deflection spectroscopy — is a kind of spectroscopy that measures the change in refractive index due to laser heating of a surface. It works via the mirage effect where a refractive index gradient exists adjacent to the substrate s surface. The test laser beam is… … Wikipedia
Optical coating — Optically coated mirrors and lenses. An optical coating is one or more thin layers of material deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light. One type of optical… … Wikipedia
Evolution of the eye — The evolution of the eye has been a subject of significant study, as a distinctive example of a homologous organ present in a wide variety of taxa. The development of the eye is considered by some experts to be monophyletic; that is, all modern… … Wikipedia
Potassium chloride — This article is about the chemical compound. For other uses, see KCL. Potassium chloride … Wikipedia
Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams … Wikipedia
