Abstract
Systems and methods are provided for a solid filled mirrored lens system capable of wider fields of view and wider spectra than current lens systems. The mirrored lens is used to focus light incident upon a right circular cylindrical central body comprising a substantially planar first surface and a substantially planar second surface. A primary reflecting surface is located on the second surface of the central body and shaped as an annulus with a void in the central region of the second surface. Further, a secondary reflecting surface is located in a central region of the first surface facing the primary reflecting surface.
