A pair of optical filters that are designed and optimized for viewing 3D photos printed on home computer inkjet printers. The pair has a red colored filter having a transmittance (10) of greater than 60 % with 610 nm and greater wavelength light, and a cyan colored filter having a transmittance peak (12) of greater than 60 % with 480 nm wavelength lights and a transmittance of greater than 50 % with 700 nm (14) and greater wavelength.

La présente invention concerne une paire de filtres optiques qui sont conçus et optimisés pour visualiser des photos 3D imprimées sur des imprimantes à jet d'encre d'ordinateurs personnels. La paire comprend un filtre de couleur rouge présentant un facteur de transmission supérieur à 60 % à une lumière de longueur d'onde supérieure ou égale à 610 nm, ainsi qu'un filtre de couleur cyan présentant un pic du facteur de transmission supérieur à 60 % à une longueur d'onde de 480 nm et un pouvoir de transmission supérieur à 50 % à une lumière de longueur d'onde supérieure à 700 nm.
