Shaping the Beam
The beam can be shaped using patterns and the shutters. The beam can also be colored with
colored glass in the pattern holder.
Pattern and Color Projection
The two pattern holder slots are inside the fixture and immediately in front of the shutters. The
holder slots accommodate B-size and glass pattern holders. The holder holds 2.5 and 2.75 inch
diameter patterns. One pattern holder for steel patterns is supplied with the fixture. Additional glass
or steel pattern holders are available from ETC.
Figure-9 Pattern Holder Dimensions.

Figure-10 Pattern Holder Location.
N o t e : The projected beam is the inverse of the inserted patterns and shutter
adjustments. That is, for a pattern to be projected right side up, it is inserted upside
down and backwards. Likewise, moving a shutter affects its opposite image.
