| paraboloid | <geometry> The solid generated by the rotation of a parabola about its axis; any surface of the second order whose sections by planes parallel to a given line are parabolas. The term paraboloid has sometimes been applied also to the parabolas of the higher orders. Origin: Parabola: cf. F. Paraboloide. Source: Websters Dictionary (01 Mar 1998) |

| paraboloid condenser | A type of dark-field condenser. (05 Mar 2000) |
| paraboloid dark field condenser | <microscopy> A lens of parabolic shape. The vertex end is ground back so that its focus can be brought into coincidence with the specimen on the slide. A central stop is provided to block the central rays. It is used chiefly for medium- power work. (05 Aug 1998) |
| condenser, darkfield, paraboloid | <microscopy> A dark field condenser consisting of a reflecting surface in the form of a segment of a paraboloid of revolution. Parallel rays entering the condenser around the periphery of the central stop are reflected from the curved surfaces and converge at the focus of the paraboloid. See (05 Aug 1998) |
