Front Screen Installations
There are two basic screen types: flat and curved. The choice between a flat
screen or a curved screen is dependent on audience viewing angle and screen
gain. There is always a trade-off between viewing angle and gain. Viewing
angles for both screen types are illustrated in Figures 2.1 and 2.2 (plan views).
Flat screens offer a gain of about 1 with a viewing angle just less than 180°.
Incident light reflects equally in all...

Rear Screen Installations
There are two basic types of rear screens: diffused and optical. A diffused screen
has a surface which spreads the light striking it. Purely diffused screens have a
gain of less than 1. The main advantage of the diffused screen is its wide viewing
angle, similar to that of a flat screen for front screen projection. Optical screens
take light from the projector and redirect it to increase the light intensity at the
front of the...

Outside windows are undesirable in any projection room. A small crack between
curtains on a sunny day can wash out a projected image. If you do have
windows, make sure that window coverings are opaque and overlapping — some
window coverings are designed to provide up to 100 percent blockage of outside
light. Ideally, the material should have a matte finish.
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the...

temperature can cause drifts in the projector circuitry which may affect
performance.
· Keep the projector away from devices which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide
projectors, speakers, power amplifiers, elevators, etc.
· For rear screen applications, less space is required if a mirror is used to fold
the optical path.
· Choose the right screen size for the application:

Throw distance is roughly equal to the width of the screen multiplied by the type
of lens you are using. For example, if using a 1.2:1 lens, throw distance should
be roughly equal to 1.2 
x the screen width. Once you know your screen size, you
can determine how far away the projector should be:

Lens Type Approx. Throw Distance
5:1 5 x screen width
1.2:1 1.2 x screen width
