optical axis [′äp·tə·kəl ′ak·səs]

(anatomy)

An imaginary straight line passing through the midpoint of the cornea (anterior pole) and the midpoint of the retina (posterior pole).

(optics)

A line passing through a radially symmetrical optical system such that rotation of the system about this line does not alter it in any detectable way.

Optical Axis

The optical axis of a lens or a concave or convex mirror is the straight line that is the axis of symmetry of the refracting surfaces of the lens or of the reflecting surface of the mirror. It passes perpendicularly through the center of these surfaces. Optical surfaces that have such an axis are said to be axially symmetric. The optical axis of an optical system is the common axis of symmetry of all the lenses and mirrors in the system.

Panasonic Introduces New SD Memory Card Camcorders In Middle East by Albawaba.com The position of the reducer along the optical axis is not of paramount importance--there is a very high flexibility in this--but another aspect of the parachromat is that we can assume that the reduction lens is an objective lens with a weak lens placed in front of it, somewhat spoiling the correction.
