Shaping the beam
The beam can be shaped using the shutters (see
Figure 8
), a pattern, an optional drop-in iris, or by
rotating the barrel.
Pattern Projection
The pattern holder slot is on the top side of the barrel and in front of the shutters. It accommodates
A-size, B-size
and glass pattern holders (see
Figure 7
).
Use an optional donut in the accessory holder to enhance pattern projection. Donut diameter range
should be 6.35 cm to 6.98 cm.
Drop-In Iris Slot
The drop-in iris slot is located on the top of the barrel and in front of the pattern holder slot. It
accommodates either a drop-in iris or a motorized pattern device. When the slot is not in use, a
small sheet metal cover secured with two screws prevents light leakage (see
Figure 8
).
Step 1:
Use a screwdriver to loosen the screws on the drop-in iris slot cover.

Step 2:
Slide the cover completely forward to expose the slot.
Step 3:
Insert the iris or motorized pattern device. For an iris, install the flat side toward the
shutters and make sure the iris handle extends from the slot.
Step 4:
Slide the slot cover back toward the shutters until it meets the iris handle. Leave enough
space to move the iris handle.
Step 5:
Secure the drop-in iris slot cover by tightening the screws.
