Method of manufacturing lens array plate, erecting equal-magnification lens array plate, and optical scanning unit, and image reading device
摘要:
A method of manufacturing a lens array plate includes: forming a light shielding film on a flat surface of a dielectric substrate; forming a plurality of convex lenses on the flat surface of the dielectric substrate by press molding the dielectric substrate with the light shielding film; and forming a stack of two lens array plates manufactured by press molding. The light shielding film is not formed in a lens formation area in which the convex lens is formed.
