Sagittal rays intersect the pupil along a line that is perpendicular to the meridional plane for the ray's object point and passes through the optical axis. If the axis direction is defined to be the z axis, and the meridional plane is the y - z plane, sagittal rays intersect the pupil at yp =0. 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 the type of system they are used to model. 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.

"WebAll rays coming from the same point will intersect in one place at some point. So all points that are parallel to the lens at a distance (o) will intersect in one place. Where they intersect is when the camera is in focus. So, you can use the thin lens approximation to find where the medial ray and parallel ray intersect. " - Can rays intersect
