Scientific paper

Finite element models are often used to predict the optical performance of a structure under a wide variety of conditions. A technique is described in this paper which couples the equations of optics to the finite element model. It assumes only that each optical lens or mirror is a rigid mass so that motion of the vertex defines motion of the element. Examples are drawn from the Space Telescope project.
