Hii mate
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 are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror,however the cardinal points are widely used to approximate the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations.
The cardinal points of a thick lens in air. F, F' front and rear focal points, P, P' front and rear principal points, V, V' front and rear surface vertices.
I hope this helps u!

Cardinal points of thick lens:
• In Gaussian optics, the cardinal points involve of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system.
• These are the nodal, principal points, and the focal points
• The cardinal points of thick lens lie on the optical axis of the optical system. Each point is distinct by the effect the optical system has on rays that pass through that point, in the paraxial approximation.
