Abstract
An optical scanning device, for reflecting a light beam produced by a laser light source, having an entrance window; a rotatable scan optic having a reflective surface and a spherical exit window; the reflective surface of the rotatable scan optic positioned adjacent the entrance window and central to the spherical exit window such that the light beam successively encounters the entrance window, the reflective surface of the rotatable scan optic, and the spherical exit window surrounding the reflective surface of the rotatable scan optic, the light beam encountering and passing through the spherical exit window after being reflected away from the rotatable scan optic; the reflective surface of the rotatable scan optic circumscribed by a chamber defined by the entrance window, the rotatable scan optic device, and the spherical exit window.
