SUMMARY - Draper Vortex Rear Video Projector Screen
The Vortex is a marriage of the best features of two rear screen technologies— optical and diffusion. A 0.5 mm Fresnel lens gathers the light from the projector and directs it at a right angle through the screen. As the light exits the screen on the audience side, a diffusion medium redistributes the light evenly in all directions—up, down, left, right and center. It features superior resolution, superb color contrast, an exceptionally wide viewing cone in both the horizontal and vertical axes, extraordinary center-to-corner brightness ratio, and uniform brightness without hot spots. It is designed for use with single lens projectors and the charcoal grey tint provides superior color contrast even under harsh ambient light. Gain 2.0
