The change in the direction of ray of light, heat, or the             like, when it enters obliquely a medium of a different             density from that through which it has previously moved.                         Refraction out of the rarer medium into the denser,                      is made towards the perpendicular.      --Sir I.                                                                               Newton.          3. (Astron.)             (a) The change in the direction of a ray of light, and,                   consequently, in the apparent position of a heavenly                   body from which it emanates, arising from its passage                   through the earth's atmosphere; -- hence distinguished                   as atmospheric refraction, or astronomical refraction.             (b) The correction which is to be deducted from the                   apparent altitude of a heavenly body on account of                   atmospheric refraction, in order to obtain the true                   altitude.          {Angle of refraction} (Opt.), the angle which a refracted ray             makes with the perpendicular to the surface separating the             two media traversed by the ray.          {Conical refraction} (Opt.), the refraction of a ray of light             into an infinite number of rays, forming a hollow cone.             This occurs when a ray of light is passed through crystals             of some substances, under certain circumstances. Conical             refraction is of two kinds; external conical refraction,             in which the ray issues from the crystal in the form of a             cone, the vertex of which is at the point of emergence;             and internal conical refraction, in which the ray is             changed into the form of a cone on entering the crystal,             from which it issues in the form of a hollow cylinder.             This singular phenomenon was first discovered by Sir W. R.             Hamilton by mathematical reasoning alone, unaided by             experiment.          {Differential refraction} (Astron.), the change of the             apparent place of one object relative to a second object             near it, due to refraction; also, the correction required             to be made to the observed relative places of the two             bodies.          {Double refraction} (Opt.), the refraction of light in two             directions, which produces two distinct images. The power             of double refraction is possessed by all crystals except             those of the isometric system. A uniaxial crystal is said             to be optically positive (like quartz), or optically             negative (like calcite), or to have positive, or negative,             double refraction, according as the optic axis is the axis             of least or greatest elasticity for light; a biaxial             crystal is similarly designated when the same relation             holds for the acute bisectrix.          {Index of refraction}. See under {Index}.          {Refraction circle} (Opt.), an instrument provided with a             graduated circle for the measurement of refraction.          {Refraction of latitude}, {longitude}, {declination}, {right       ascension}, etc., the change in the apparent latitude,             longitude, etc., of a heavenly body, due to the effect of             atmospheric refraction.          {Terrestrial refraction}, the change in the apparent altitude             of a distant point on or near the earth's surface, as the             top of a mountain, arising from the passage of light from             it to the eye through atmospheric strata of varying             density.

Micrometer \Mi*crom"e*ter\, n. [Micro- + -meter: cf. F.       microm[8a]tre.]       An instrument, used with a telescope or microscope, for       measuring minute distances, or the apparent diameters of       objects which subtend minute angles. The measurement given       directly is that of the image of the object formed at the       focus of the object glass.          {Circular, [or] Ring}, {micrometer}, a metallic ring fixed in             the focus of the object glass of a telescope, and used to             determine differences of right ascension and declination             between stars by observations of the times at which the             stars cross the inner or outer periphery of the ring.          {Double image micrometer}, a micrometer in which two images             of an object are formed in the field, usually by the two             halves of a bisected lens which are movable along their             line of section by a screw, and distances are determined             by the number of screw revolutions necessary to bring the             points to be measured into optical coincidence. When the             two images are formed by a bisected object glass, it is             called a divided-object-glass micrometer, and when the             instrument is large and equatorially mounted, it is known             as a heliometer.          {Double refraction micrometer}, a species of double image             micrometer, in which the two images are formed by the             double refraction of rock crystal.          {Filar, [or] Bifilar}, {micrometer}.
