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 3-6. The position of the projector and

dealer for assistance.

1. With no vertical or horizontal lens shift, the lens center and screen center are aligned with each
other.
2. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of
the screen width.
3. Vertical lens shift figures apply to ceiling mount configurations. For floor installations
(where the projector is upright), reverse the up/down vertical offset percentages.
