[Middle English, from Old French, diminutive of double, double; see double.]doublet (ˈdʌblɪt) n1. (Clothing & Fashion) (formerly) a man's close-fitting jacket, with or without sleeves (esp in the phrase doublet and hose)2. a. a pair of similar things, esp two words deriving ultimately from the same source, for example reason and ratio or fragile and frailb. one of such a pair3. (Jewellery) jewellery a false gem made by welding a thin layer of a gemstone onto a coloured glass base or by fusing two small stones together to make a larger one4. (General Physics) physics a. a multiplet that has two membersb. a closely spaced pair of related spectral lines5. (Games, other than specified) (plural) two dice each showing the same number of spots on one throw6.

n. 1. a close-fitting jacket, sleeved or sleeveless, sometimes with a short skirt, worn by men in the Renaissance. 2. a pair of like things; couple. 3. one of a pair of like things; duplicate. 4. a unit composed of two closely or identically matched pieces, as an artificial gem. 5. one of two or more words in a language that are derived from the same source, esp. through different routes, as coy and quiet, both taken from the same Latin word, quiet directly and coy by way of Old French. 6. doublets, a throw of a pair of dice in which the same number of spots turns up on each die. 7. a compound lens made of two thin lenses shaped so as to reduce chromatic and spherical aberrations.

Physics two simple lenses designed to be used together, the optical distortion in one being balanced by that in the other doublet[′dəb·lət] (atomic physics) Two stationary states which have the same orbital and spin angular momentum but which have different total angular momenta, and therefore have slightly different energies due to spin-orbit coupling. (electromagnetism) dipole (fluid mechanics) A source and a sink separated by an infinitesimal distance, each having an infinitely large strength so that the product of this strength and the separation is finite. (optics) A lens made up of two components, especially an achromat. (particle physics) Two elementary particles which have slightly differing masses and the same baryon number, spin, parity, and charge conjugation parity (if self-conjugate), but have different charges. (physical chemistry) Two electrons which are shared between two atoms and give rise to a nonpolar valence bond. (spectroscopy) Two closely separated spectral lines arising from a transition between a single state and a pair of states forming a doublet as described in the atomic physics definition. doublet
