The marginal ray (sometimes known as an a ray or a marginal axial ray) in an optical system is the meridional ray that starts at the point where the object crosses the optical axis, and touches the edge of the aperture stop of the system. This ray is useful, because it crosses the optical axis again at the locations … See more In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of See more There are many special rays that are used in optical modelling to analyze an optical system. These are defined and described below, grouped by … See more A light ray is a line (straight or curved) that is perpendicular to the light's wavefronts; its tangent is collinear with the wave vector. Light rays in homogeneous media are straight.

WebDec 1, 2024 · A skew ray is any ray that is not meridional (the ray neither has a common point with nor is parallel to the optical axis) [3]. Besides, the focus position of a lens depends on the distance, with respect to the optical axis, of the ray arriving at the lens. Namely, the focus positions are different for the meridional, marginal and paraxial rays ...
