WebbIn geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens ). [1] [2] A paraxial ray is a ray which makes a small angle ( θ) to the optical axis of the system, and lies close to the axis throughout the system.
