Folded Optics
In rear-screen applications where space behind the projector is limited, a mirror may be
used to fold the optical path, as shown in Figure 3-5. The position of the projector and
mirror must be accurately set. If you are considering this type of installation, contact your
dealer for assistance.

the screen width.
2. Vertical lens shift figures apply to ceiling mount configurations. For floor installations
(where the projector is upright), reverse the up/down vertical offset percentages.
3. Lens shift is not possible in any direction with the Telesto A lens. The vertical position is fixed at
50% down.
