Title: Elliptic cylindrical baffle assembly

Abstract: An assembly for baffling an associated optical system from off-axis radiation and, at the same time, reducing the thermal load by minimizing radiation absorption within the assembly. In its most basic embodiment, the assembly comprises: a rectangularly-shaped box-like housing having a specular internal surface; and, specular baffles that are sections of surfaces of hollow elliptic cylinders and that are positioned within the housing in spaced-apart relationship to each other and in a one-behind-the-other arrangement, and also are perpendicular to the sides of the housing.
