| spheric | 1. Having the form of a sphere; like a sphere; globular; orbicular; as, a spherical body. 2. Of or pertaining to a sphere. 3. Of or pertaining to the heavenly orbs, or to the sphere or spheres in which, according to ancient astronomy and astrology, they were set. "Knaves, thieves, and treachers by spherical predominance." (Shak) "Though the stars were suns, and overburned Their spheric limitations." (Mrs. Browning) Spherical angle, Spherical coordinate, Spherical excess, etc. See Angle, Coordinate, etc. Spherical geometry, that branch of geometry which treats of spherical magnitudes; the doctrine of the sphere, especially of the circles described on its surface. Spherical harmonic analysis. See Harmonic, Spherical lune,portion of the surface of a sphere included between two great semicircles having a common diameter. Spherical opening, the magnitude of a solid angle. It is measured by the portion within the solid angle of the surface of any sphere whose center is the angular point. Spherical polygon,portion of the surface of a sphere bounded by the arcs of three or more great circles. Spherical projection, the projection of the circles of the sphere upon a plane. See Projection. Spherical sector. See Sector. Spherical segment, the segment of a sphere. See Segment. Spherical triangle,re on the surface of a sphere, bounded by the arcs of three great circles which intersect each other. Spherical trigonometry. See Trigonometry. Spher"ically, Spher"icalness.

| spherical aberration | <microscopy> A lens defect in which image forming rays passing through the outer zones of the lens focus at a distance from the principal plane, different from that of the rays passing through the centre of the lens. The aberration caused by (near-paraxial) monochromatic light rays or electron beams passing through different radii of a lens not coming to the same focus. (05 Aug 1998) |

| spherical nucleus | Spinal nucleus of accessory nerve, a slender column of motor neurons extending longitudinally through the central part of the ventral horn of the upper five segments of the spinal cord, giving origin to the spinal part of the accessory nerve. Synonym: nucleus spinalis nervi accessorii, globosus nucleus. (05 Mar 2000) |

| spherical aberration |
A lens fault which results in degraded image quality at the film plane. It is caused by light rays passing through the lens from a single point on the optical axis focused at different points according to incident height. Spherical aberration can be reduced by stopping down the lens.
