Abstract: This is to shed light on a glass composition suitable for a thin lens, and provide a lens (an optical component) manufactured with using the glass. A concave lens as an optical component is made of glass containing 12 to 16% of B2O3, 35 to 44% of La2O3, and 3 to 8% of ZnO, expressed as wt %. The concave lens has a thickness t1 in its center portion of 0.5 mm or less, and a ratio (W/t1) of an external diameter W with respect to the thickness t1 of 24 or more. The concave lens can be produced suitably by press forming.

Abstract: An optical element includes: an optically functional part having a first convex surface and a second convex surface intersecting with an optical axis and facing opposite to each other; and an outer peripheral part provided around the optically functional part, the outer peripheral part having a first outer peripheral surface extending from a periphery of the first convex surface and a second outer peripheral surface extending from a periphery of the second convex surface. The first outer peripheral surface and the second outer peripheral surface each are formed to be tapered. A thickness of the outer peripheral part in an optical axis direction is reduced toward a direction moving away from the optical axis.

Abstract: A cemented optical element includes a convex lens and a concave lens. The convex lens has a first convex surface and a second convex surface that are rotationally symmetric with respect to an optical axis. The convex lens has an edge with a thickness of substantially zero. The concave lens has a concave surface bonded to the first convex surface of the convex lens. Preferably, the peripheral portion of the concave lens extends radially outwardly beyond the convex lens to the extent that it is located within an area surrounded by an extension zone of the second convex surface of the convex lens.
