Shaping the beam
The beam can be shaped using the shutters (see
Figure 1
, a pattern or an optional drop-in iris.
Pattern Projection
The pattern holder slot is on the top side of the barrel and in front of the shutters. It accommodates
an
M-size pattern holder
(see
Figure 7
). The pattern holder handle can be bent away from the
shutter handle to keep it from interfering with the action of the shutter handle.
Use an optional donut in the accessory holder to enhance pattern projection. Donut diameter range
should be 2.5” to 2.75”.
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 Phillips screws prevents light leakage (see
Figure 8
).
Step 1:
Use a Phillips screwdriver to loosen the screws on the drop-in iris slot cover.
Do not
remove screws.
Step 2:
Slide the cover completely forward to expose the slot.
Step 3:
Insert the iris with 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.
