Abstract: front page image
(EN)There is provided an optical member having a low reflectance and a good dustproof property. An optical member includes a base and a porous layer disposed on the base and including a plurality of pores. A plurality of projections are formed on a surface of the porous layer. The width of the projections is larger than the pore size of the pores of the porous layer. The distance between the projections is 75 nm or more and 300 nm or less.
(FR)L'invention porte sur un élément optique ayant un faible facteur de réflexion et une bonne propriété anti-poussière. L'élément optique comprend une base et une couche poreuse disposée sur la base et comprenant une pluralité de pores. Une pluralité de parties saillantes sont formées sur une surface de la couche poreuse. La largeur des parties saillantes est plus grande que la taille de pore des pores de la couche poreuse. La distance entre les parties saillantes est supérieure ou égale à 75 nm et inférieure ou égale à 300 nm.
