| principal plane | <microscopy> A plane normal to the principal axis of a lens, passing through a principal point. In geometrical construction of ray diagrams through a perfect lens, the single plane that can be considered (disregarding the refraction of the rays at each optical interface) to convert paraxial rays into rays converging onto the rear focal point. For thin symmetrical lenses, there is one principal plane that bisects the lens. For thick or complex lenses, there is a principal plane for the paraxial ray to the left, and another for the paraxial ray to the right, of the lens. (05 Aug 1998) |
|---|
| axis, principal | <microscopy> A line conceived as passing through the centre of a lens to connect the centres of curvature of the lens surfaces. The focal points of a lens lie on the principal axis. (05 Aug 1998) |

| principal | 1. Highest in rank, authority, character, importance, or degree; most considerable or important; chief; main; as, the principal officers of a Government; the principal men of a state; the principal productions of a country; the principal arguments in a case. "Wisdom is the principal thing." (Prov. Iv. 7) 2. Of or pertaining to a prince; princely. Principal axis. See Axis of a curve, under Axis. Principal axes of a quadric, a plane passing through the optical axis of a crystal. Origin: F, from L. Principalis. See Prince. Source: Websters Dictionary (01 Mar 1998) |
| principal artery of thumb | <anatomy, artery> Origin, radial (deep palmar (arterial) arch); distribution, palmar surface and sides of thumb; anastomoses, arteries on dorsum of thumb. Synonym: arteria princeps pollicis, chief artery of thumb, princeps pollicis, principal artery of thumb. (05 Mar 2000) |
| principal focus | The real or virtual meeting point of rays passing into a lens parallel to its axis. (05 Mar 2000) |
| principal investigator | The head researcher responsi for organising and overseeing a clinical trial (09 Oct 1997) |
| principal islets | Separate globular aggregates made up mostly of endocrine pancreatic tissue; present in some fishes and snakes. (05 Mar 2000) |
| principal optic axis | A line passing through the centre of the lens of a refracting system at right angles to its surface. (05 Mar 2000) |
| principal point | <microscopy> Mutually conjugate points lying on the lens axis and producing a magnification of one. Object and image distance as well as focal length are calculated (measured) from these points. (05 Aug 1998) |
| principal sensory nucleus of the trigeminus | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |
| principal sensory nucleus of trigeminal nerve | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |
| focus, principal | <physics> The point at which a lens focuses an axial object point. Synonymous with focal point. (05 Aug 1998) |
| Aeby's plane | In craniometry, a plane perpendicular to the median plane of the cranium, cutting the nasion and the basion. (05 Mar 2000) |
| aperture plane | <microscopy> In a microscope adjusted for Koehler illumination, the conjugate planes that include the light source, the condenser iris diaphragm, the objective lens back aperture, and the eye point. Spaces in the aperture planes are the reciprocal of those in the field planes. (05 Aug 1998) |
| auriculo-infraorbital plane | A standard craniometric reference plane passing through the right and left porion and the left orbitale; drawn on the profile radiograph or photograph from the superior margin of the acoustic meatus to the orbitale. Synonym: auriculo-infraorbital plane, eye-ear plane, Frankfort horizontal plane, Frankfort plane, infraorbitomeatal plane. (05 Mar 2000) |
| axial plane | Transverse plane, as in CT scanning. Synonym: transaxial plane. (05 Mar 2000) |
| principal plane |
(Also called sun's meridian or sun's vertical.) In clear-sky optics, the vertical plane defined by sun, zenith, and observer. The clear daytime sky's radiance, polarization, and chromaticity patterns are largely symmetric about the principal plane.
