| 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 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) |
| 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 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.

| principal point |
The point on the earth where a satellite sensor is focused at any time during its orbit. If the sensor vertical axis is perpendicular to the earth's surface, the principal point coincides with the subpoint. 2. A term used in remote sensing; the point where the optical axis intersects the principal plane.
