3.3 Shaping the beam
The beam can be shaped using a pattern holder (PFGOBO1) or an optional drop-in iris (PFIRIS1).
• The pattern holder slot is on the top side of the barrel and in front of the shutters, and it is the same of iris.
• The drop-in iris slot is located on the top of the barrel and in front of the pattern holder slot. It accommo-
dates either a drop-in iris. When the slot is not in use, a small sheet metal cover secured with two screws
prevents light leakage.
1. Loosen the screws on the drop-in iris slot cover. Do not remove thumbscrews.
2. Slide completely forward to expose the slot.
3. Insert the iris, with the flat side toward the shutters and make sure the iris handle extends from the slot.
4. Slide the slot cover back toward the shutters until it meets the iris handle. Leave enough space to move
the iris handle.
5. Secure the drop-in iris slot cover by tightening the screws.
