Title (EN) ULTRA-BRIGHT LIGHT ENGINE FOR PROJECTION DISPLAYS
(FR) MOTEUR DE LUMIERE ULTRA-BRILLANTE POUR AFFICHAGES DE PROJECTION
Abstract: front page image
(EN)A projector incorporating a prism and a plurality of light valves for modulating light that passes through the prism, wherein the color splitting-converging prism includes a dichroic coating having multiple layers of high and low index of refraction and 1/4 wavelenth thickness at each desired angle of incidence for reducing dichoric shift and thereby minimizing light loss.
(FR)L’invention concerne un projecteur comprenant un prisme et une pluralité de modulateurs de lumière pour moduler la lumière qui passe à travers le prisme. Ledit projecteur comprend un prisme discriminateur-convergeur de couleurs qui possède un revêtement dichroïque ayant des couches multiples à fort et à faible indice de réfraction et une épaisseur d’un quart d’onde à chaque angle d’incidence souhaité pour réduire le transfert dichroïque et ainsi minimiser la perte de lumière.
