| Title: |
Stage Lighting Methods and Apparatus |
| Abstract: |
Spot illumination apparatus and methods are described. According to one
implementation a spot luminaire includes a light source for emitting a
beam of light and a projection lens 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 is positioned proximate the first
field stop and is adapted for selectively moving at least one variable
density filter across the beam of light. A relay lens group is positioned
between the first field stop and the projection lens. The relay lens
group is configured to prevent the at least one variable density filter
from being imaged by the projection lens. Methods for providing stage
lighting are also described.
