Light Tunnel ™

Light Tunnel™ for Projection Display

Unlike competitor products, the Materion Balzers Optics hollow integrator LightTunnel™ creates enhancement of light uniformity by outstanding reflection. Used for light integration in projection systems employing DLP™ technology, its compact design establishes a new standard for por table projection systems. We apply our patented Silflex™ HLE7 silver coating or 400 Deflex™ 75 dielectric coating to the internal surfaces of the LightTunnel™ giving it unique advantages.

Benefits

Enhanced light uniformity by high reflection
Reduced flickering effects
Reduces length of solid glass integrator rods by 50%
Exhibits less sensitivity to dust
Compact design for ultra compact projection displays
No impact on color

Applications

Light integration in por table business and large venue projection systems employing DLP™ technology.
