FRONT PROJECTION PARTIAL DOME SCREENS
Stewart Filmscreen offers unique custom air plenum domes up to a 50-degree vertical by 360-degree horizontal field of view. Each system is individually designed and built to the particular perimeters required for each project. The domes utilize seamless screen material (up to 40' by 90') that is held into its design shape by a small active vacuum, plenum chamber and proximity sensor. The systems are lightweight relative to their size and can be built to be transportable. In the event that the viewing surface is ever damaged and in need of replacement, a new screen can be installed in just a few hours in order to minimize valuable simulator down time.
COMPOUND CURVED SCREENS FOR COLLIMATED OPTICS
In critical training applications, such as commercial aircraft cockpits, where multiple viewers are situated adjacent to each other on either side of the screen centerline, it is imperative that each viewer’s perspective of the displayed virtual images be accurate and consistent with actual conditions one would experience in real life scenarios. With the use of compound curved front surface mirrors and rear projection screens, the optical light path can be collimated to create a realistic perspective to multiple viewers.
The Nordam Group of Tulsa, Oklahoma, manufactures of compound curved acrylic shells, and Stewart Filmscreen have teamed their efforts to deliver the worlds most advanced and popular compound curved rear projection screens.
CURVED CYLINDER DISPLAY
Single Axis curved screens address multiple channel projection displays where soft edge blending is employed to create a continuous seamless vista. Stewart Filmscreen can manufacture the screen and supporting frame structure to the specified radius, size and optical screen gain requirements. Cylinder screens are available in hard rigid substrates or flexible screen membrane suspended in an aluminum frame.
SEGMENTED FLAT PANEL SCREENS - FRONT PROJECTION
Completely freestanding screen and frame systems built to specific project requirements. The simplest way to display multiple projected images is front projection screens arranged as segmented flat panels. The flexible screen surface wraps around the front and side edges of the screen frame to conceal from the viewer the screen support frames. This attachment design allows each projected image to adjoin with the adjacent display screens. Under projection, only a hairline seam is evident to the viewer between each image.
Stewart Filmscreen manufactures various screen reflectance gains for the above mounting system to accommodate any LCD, DLIA or CRT projectors. Each individual screen segment can be manufactured up to 18’ by 24’, utilizing a seamless screen surface.
SEGMENTED FLAT PANEL SCREENS - REAR PROJECTION
A most versatile simulation display technique is the segmented rear projection screen. Each screen panel can be manufactured in a variety of shapes and sizes to accommodate display scenarios ranging from a M-2 DART type system to a full vista 360 degree air traffic control (ATC) simulator.
Stewart Filmscreen’s proprietary cantilevering wedge screen framing system allows each image to be rear projected completely to the outer edge of the seam – which minimizes the apparent seam gap between all adjacent images.
Whatever the project requirements, Stewart Filmscreen can meet your needs with its full line of rear projection screens. Screen choices includes: Stewart acrylic diffusion, fresnel lenticular lens or weight saving flexible diffusion.
When floor space is limited behind the screens, consider folding the projector optics with front surface mirrors. Stewart Filmscreen can design, build, and deliver turnkey front surface mirror systems, including projector stands and projector mounts.
