WebThere is an invariant associated with the path of a skew ray through an axisymmetric optical system. Let S be the shortest distance between the ray and the axis—that is, the length of the common perpendicular—and let g be the angle between the ray and the axis. Then the quantity is an invariant through the whole system.

Violation of the Lagrange invariant in an optical imaging system
WebThe n2AΩ product is proportional to the square of the Lagrange invariant. The square is due to the fact that the A product involves areas, and the Lagrange invariant is a linear measure. This quantity is known as the Basic Throughput and is invariant. In air, the AΩ product is called the Throughput of the system, and it is also invariant. WebFirst order optical system design using rays is useful for the initial design of an optical imaging system, but does not predict the energy and resolution of the system. This module introduces Gaussian beams, a specific example of how the shape of the light evolves in an imaging system. The Lagrange invariant 4:25. The post-doc's tale 4:45.
