Abstract

La presente se refiere a espejos dicroicos, también conocidos como filtros opticos. En particular, el espejo retrovisor comprende un sustrato vítreo recubierto con un apilamiento de capas de interferencia y una capa metálica reflectante. El apilamiento de capas incluye, sucesivamente desde el sustrato, i) una capa de material de elevado índice de refraccion en la zona de 1,9 a 2,8; i) una capa de material de bajo índice de refraccion en la zona de 1,2 a 2; iii) una capa de material semiconductor que tiene un índice de refraccion de mas de 3; difiriendo los índices de refraccion de los materiales de elevado índice de refraccion y de los materiales de bajo índice de refraccion en al menos 0,2, y el sustrato recubierto tiene una transmitancia a 550 nm. de al menos 6%, preferiblemente al menos 8%, y una reflectancia a 550 nm. mayor que 45%, preferiblemente mayor que 50%.This refers to dichroic mirrors, also known as optical filters. In particular, the rearview mirror comprises a vitreous substrate coated with a stack of interference layers and a reflective metal layer. The layer stacking includes, successively from the substrate, i) a layer of high refractive index material in the area of 1.9 to 2.8; i) a layer of low refractive index material in the area of 1.2 to 2; iii) a layer of semiconductor material that has a refractive index of more than 3; the refractive indices of the high refractive index materials and the low refractive index materials differing by at least 0.2, and the coated substrate has a transmittance at 550 nm. of at least 6%, preferably at least 8%, and a reflectance at 550 nm. greater than 45%, preferably greater than 50%.
