| 摘要 | A lens array includes a transparent substrate arranged on a plane perpendicular to an optical axis, first lenses, which are arranged in a main scanning direction with respect to an light incident on the transparent substrate, and which condense the light, light shielding portions arranged on the transparent substrate except in areas of the first lenses to shield the light, and second lenses, which are laminated on the first lenses, and which are made of a material with a wettability different from that of a material of the first lenses. | ||

| 主权项 | 1. A lens array comprising: a transparent substrate arranged on a plane perpendicular to an optical axis; first lenses arranged on the transparent substrate, and configured to condense a light irradiated from an object point; light shielding portions arranged on the transparent substrate except in areas of the first lenses to shield the light irradiated from the object point; and second lenses, which are laminated on the first lenses, and which are made of a material with a wettability different from that of a material of the first lenses. | ||
