Rear Screen Installations [Folded Optics]
In rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical
path, see Figure 2‐7 . The position of the projector and mirror must be accurately set ‐ if considering this type of
installation call your dealer for assistance.
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 one. The main advantage of the diffused screen is
its wide viewing angle, similar to that of a flat screen for front screen projection. This type of screen is suitable
when a wide viewing angle is required but there is low ambient room lighting. Optical screens take light from the
projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A
viewing cone, similar to that of a curved front screen installation is created. This type of screen is better suited for
brightly lit rooms where the audience is situated within the viewing cone.
