how many cardinal point are found in combination of thin lenses
Hello aspirant
There are six cardinal points in combination of thin lenses.
The locations of the six cardinal points of an existing lens may be determined by four means: the nodal slide, the foco-collimator (or swinging collimator), the two-magnifications method, and the use of the Newtonian lens formula
. The cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, Optical system. Cardinal points help to provide a way to analytically simplify a system with other components.
Hello Krishan,
There are total six cardinal point found in combination of thin lenses which are situated on the optical axis which are defined in such a way so as to facilitate the image formation by the lens system.
Hope it resolves your query.
Good Luck!
