A system is provided that includes a light source, a first mirror, a second mirror, and a support structure. The light source provides light energy along an optical path extending along an optical axis. The first mirror receives and re-directs the light energy from the light source, and pivots about an azimuth axis. The second mirror receives the re-directed light energy from the first mirror and to re-direct the light energy toward a target through a window. The support structure has a first end and a second end. The first end is mounted at a support rotation point, with the support structure rotating about the support rotation point as the first mirror pivots about the azimuth axis. The second mirror is mounted to the second end of the support structure.
