Abstract

According to one implementation of a spot illumination apparatus a spot luminaire includes a light source (117) for emitting a beam of light and a projection lens (170) configured to project the beam of light towards a distant target. A first field stop, through which the beam of light passes, is positioned between the light source and the projection lens. A filter apparatus (95) is positioned proximate the first field stop (125) and is adapted for selectively moving at least one variable density filter across the beam of light. A relay lens group (220) is positioned between the first field stop (125) and the projection lens (170). The relay lens group is configured to prevent the at least one variable density filter from being imaged by the projection lens.
