摘要： Manufacturing errors are suppressed, and the precision of positioning between an image-acquisition device and an objective lens is improved. An endoscopic image-acquisition unit includes an objective-lens-unit frame (2) that holds an objective lens; and an image-acquisition-device holding frame (3) that is fitted with the objective-lens-unit frame and that holds an image-acquisition device, wherein the objective-lens-unit frame and the image-acquisition-device holding frame are bonded and fixed with a thermosetting resin (12) that is applied to a fitting region of these frames, and wherein, of the outer surface of the frame that is located on the outer side when the objective-lens-unit frame and the image-acquisition-device holding frame are fitted together, the outer surface of the fitting region and the outer surface of the region other than the fitting region satisfy the following conditional expression: α / β > 2 where α signifies the infrared absorption rate per unit area of the outer surface of the fitting region, and β signifies the infrared absorption rate per unit area of the outer surface of the region other than the fitting region.

摘要： Excellent aberration correction, suitability for high-definition and high-pixel solid state imaging elements, a small outer diameter of an end and reduction in manufacturing cost are achieved.
A wide-angle objective optical system includes, in order from an object side to an image side: a first lens group (G1); and a second lens group (G2) having positive refractive power. The first lens group includes, in order from the object side to the image side: a first lens (L1) having negative refractive power; a second lens (L2) having a concave face as an object-side face and having negative refractive power; a brightness diaphragm (S); and a third lens (L3) having positive refractive power. The following condition expressions are satisfied: - 0.5 f / f 1 0.5 0.3 f / f 2 0.7 wherein f1, f2 and f are focal distances of the first lens group, the second lens group, and the entire wide-angle objective optical system, respectively.

摘要： In the present invention, the viewing area is sufficiently enlarged, and an adequate level of illumination light is distributed in the enlarged viewing area. Provided is a capsule endoscope in which an objective lens unit (11) includes, at the extreme object side, a lens which is a meniscus lens having negative power and disposed with the convex surface thereof towards the object side, so that the convex surface thereof faces the exterior. An illumination unit (13) includes a light source and an illumination window member (19). The light source is disposed so as to surround the circumference of the lens. The illumination window member is formed in an approximately circular ring shape that surrounds the circumference of the lens and is positioned closer to the image side than an outermost diameter section in the convex surface of the first lens, through which a light flux passes. A light-blocking member that blocks the entry of illumination light into the objective lens unit is disposed between the illumination window member and the lens. Conditional expressions (1) and (2) below are satisfied: − 10 f 1 / f − 4 0.7 d 1 / f 2 where f1 is the focal length of the lens, f is the focal length of the objective lens unit, and d1 is the distance between the lens and another lens disposed adjacent to the image side of the lens.
