WebSix cardinal points There are six points which are called cardinal points of an optical system. 1. Two Focal points 2. Two Principal points 3. Two Nodal points In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the focal points, the principal points, and the nodal points. For ideal systems, the basic imaging properties such as image size, location, and orientation … See more The cardinal points lie on the optical axis of the optical system.
