Abstract

"MONTAGEM óPTICA PARA VáLVULAS DE LUZ REFLEXIVA" A invenção refere-se a uma montagem de prisma não sensível à polarização para sistemas de visor de projeção que usam válvulas de luz reflexiva. Os sistemas compreendem uma montagem de prisma tricróico de três prismas revestidos e um divisor de feixe, conformado especialmente, trapezoidal na modalidade. Os ângulos dos prismas são otimizados para melhor separação e recombinação de cores com a menor insensibilidade de polarização. A montagem forma um arranjo óptico compacto e espectralmente eficiente para projetores de LCD reflexivos.
