Adjustments
Focusing the Beam
Two internal lenses control the size and focus of the light beam. Each lens is mounted in frames
and these frames slide along the rails. The lens frames are secured in the desired location with two
knurled thumb screws.
• The field lens is nearest the lamp and controls the width of the beam.
• The focus lens is furthermost from the lamp and controls the focus of the beam.
Figure-7 Lens Arrangement.
Step 1: Remove the barrel as described in Removing and Installing the Barrel, page 7.
Step 2: Turn the Source Four XT on and aim it at a flat surface.
Step 3: Pull the shutters outward so that the aperture is fully open. Refer to Adjusting Shutters,
page 12.

Step 4: Loosen the two knurled thumb screws on the field lens holder.
Figure-8 Thumb Screws.
Step 5: Gently slide the field lens back and forth on the rails until you get the desired width of the
beam and then finger-tighten the thumb screws.
• Moving the lens towards the lamp narrows the field angle of the beam.
• Moving the lens away from the lamp widens the field angle of the beam.
Step 6: Loosen the two knurled thumb screws on the focus lens holder.
Step 7: Gently slide the focus lens back and forth on the rails until you get the desired focus of
the beam and then finger-tighten the thumb screws.
• Moving the lens towards the lamp sharpens the focus so that the edges are hard.
• Moving the lens away from the lamp softens the focus so that the edges are soft.
Step 8: Shape the beam with the shutters and install a pattern if needed. See Shaping the Beam,
page 11.

11
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.
Step 1: Remove the barrel as described in Removing and Installing the Barrel, page 7.
Step 2: Insert the pattern into the pattern holder upside down and in reverse of the desired
projection.
Figure-10 Pattern Holder Location.
Note:
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.
