WebThe paraxial approximation of the optical sine theorem is known as the Lagrange theorem and it is written as. where Λ is called the Lagrange invariant, since it has a constant value for all optical surfaces in the optical system. The principal ray heights are measured at the object and image planes for the optical surface being considered ... 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.
