The screen is translucent instead of oqaque, and is especially designed for rear projection. It is made in standard sizes, up to 18 feet wide, entirely in one piece without seams. Color films are especially brilliant on the Trans-Lux screen.




A special Trans-Lux wide angle lens makes possible the projection of a picture from behind the screen, with only one foot behind the screen for every foot of width of the picture. In other words, a 15-foot picture requires only 15 feet from lens to screen. Three and a half times this distance would be required with an ordinary projection lens.

The Trans-Lux lens contains a special prism which reverses the picture without having to reverse the film. Standard projectors and Sound heads can be used, and the film is threaded through the projector in the usual manner. The two projectors are placed at an angle so that the lenses are only a foot apart and on a level with the center of the screen.
