screen is exactly mounted onto the Atlas Structure.
!
Fresnel Lens
The screen consists of a Fresnel lens and a Front Element Screen. The Fresnel lens deflects the
light coming from the projection lens system such that it falls perpendicularly onto the front
element screen.
!
Front Element
The front element screen guarantuees that the light is distributed horizontally and vertically,
while maintaining a high contrast.
!
Texture of Surface
The surface of the screen has a special non-glare texture. This texture minimizes the direct re-
flection of the light of the surrounding and contributes also to the high contrast of the screen.
