Abstract
In one aspect, an apparatus includes a first aspheric refractive surface defined by a first polynomial and positioned to receive input light, and a first aspheric mirror surface comprising a first reflective coating, the first mirror surface defined by a second polynomial and positioned to receive light from the first aspheric refractive surface. The apparatus includes a second aspheric mirror surface comprising a second reflective coating, the second aspheric mirror surface defined by a third polynomial and positioned to receive light from the first aspheric mirror surface, and a second aspheric refractive surface defined by a fourth polynomial and positioned to receive light from the second aspheric mirror surface, wherein the first aspheric refractive surface, the first aspheric mirror surface, the second aspheric mirror surface, and the second aspheric refractive surface are arranged to have a fixed alignment with respect to each other as part of a monolithic structure.
