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
mirror must be accurately set. If you are considering this type of installation, contact your
dealer for assistance.

Other Considerations Other considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature may cause
drifts in the projector circuitry, which may affect performance.
• Keep the projector away from devices that radiate electromagnetic energy such as
motors and transformers. Common sources of these include slide projectors,
speakers, power amplifiers and elevators.
➤
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.
This is especially critical for 3D viewing; with a conventional
second-surface mirror, the resulting image quality may be
unacceptable.
