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.

For best performance, always use “first-surface” mirrors in your
rear-projection installation (as opposed to conventional,
“second-surface” mirrors with the reflective surface behind a
transparent substrate such as glass or acrylic).
First-surface mirrors provide a strict reflection without the “ghosting”
effect seen with a second surface mirror, where a faint secondary
reflection could be observed coming from the front surface of the
glass.
