摘要： To propose a hybrid lens, which does not depend on a shape and thickness of glass, which has an excellent dimensional precision, and which can be manufactured with a low cost and a method thereof. A method of manufacturing a hybrid lens includes the following steps of (a) preparing a guide component having a through hole, and a plane parallel glass plate formed of optical glass; (b) fixing the plane parallel glass plate to at least one of surface of the guide component so that the plane parallel glass plate is accommodated in the guide component; and then (c) forming a resin lens on at least one of surfaces of the plane parallel glass plate by applying and curing energy-curable resin.

摘要： An imaging module includes: an object lens; an image-sensing device; a holder that holds the object lens and the image-sensing device, the holder having a butt-contact portion with which the object lens is able to be brought into contact from an object side; and an aperture stop arranged closer to the object than the butt-contact portion, wherein an area that is to be light-shielded by an outer-periphery of the aperture stop is larger than an internal diameter of the butt-contact portion.

摘要： It is provided a lens unit to be small-sized, while reducing deterioration in optical performance after experiencing thermal expansion. The lens unit includes an aperture member, a lens, an image sensor, and a holder. A range where the aperture member abuts on a flange part of the lens overlaps with a range where the holder abuts on the flange part of the lens. A first gap is provided between a holder inclined surface of the holder and a lens inclined surface of the lens over the entire circumference. A second gap is provided between an outer circumferential surface of the lens and an inner surface of the holder over the entire circumference.
