WebThe optical axis is defined as a line extending from the vertex of the cornea through the nodal point of the eye to the posterior pole of the eye, which is, in turn, defined by the … An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens, microscope or telescopic sight. The optical axis is an imaginary line that defines the path along which light propagates through the system, up to first approximation. For a system composed of simple lenses and mirrors, the axis passes through the center of c…
