Abstract: The present disclosure describes a compact spotlight that can change the area which it illuminates. The spotlight incorporates a wide angle light source, a catadioptric lens, and a bearing system for moving the catadioptric lens, the light source, or both. Movement of the light source relative to the catadioptric lens along the optical axis can change the beam diameter of the spotlight, while providing an acceptable illumination pattern.
