Abstract
An advantageous optical apparatus with relatively large field viewing of an image to the rear of an observer is disclosed. The apparatus has two mirrors having cylindrical symmetry where the mirrors are positioned so that a plane of symmetry for each mirror is substantially coincident. The mirrors are further configured so that the apparatus has an astigmatism less than 0.0035, and a ratio between the far field and the near field magnification of less than 0.9. The apparatus is fabricated, in one embodiment, by using force to conform a thin polymer mirror onto an appropriate surface configuration on a monolithic block.
