    摘要： An endoscope has an insertion portion, an abutment portion, an increasing device and an observation portion. The insertion portion is an insertion portion which can be inserted into a subject. The abutment portion is provided at a distal end portion of the insertion portion. The abutment portion provided at the distal end portion can contact with the subject. The increasing device increases the abutment area of the abutment portion. The observation portion performs observation of the subject on the abutment portion provided at the distal end portion and having been increased by the increasing device, or performs observation of the subject spaced by a predetermined distance by the increased abutment portion.

    摘要： An illumination optical system includes a prism disposed on an incident optical axis and a lens that is disposed between the light source and an incident surface of the prism or between an emitting surface of the prism and an illuminated object, at least one of the reflection surfaces being a transmission/reflection surface. Additionally, an illumination optical system includes a prism having a surface that is disposed so as to obliquely intersect with an incident optical system, that transmits a part of the entering light to be emitted therefrom, and that deflects at least part of the rest of the light in a direction that intersects with the incident optical axis to be emitted therefrom. Furthermore, an illumination optical system has a rod lens that is disposed so that a longitudinal direction thereof is inclined with respect to an incident optical axis is provided.

    摘要： A zoom lens includes, in order from an object side, a first lens unit with positive power; a second lens unit with positive power; and a third lens unit with negative power. When the magnification of the zoom lens is varied, extending from a wide-angle position to a telephoto position, spacings between the first lens unit and the second lens unit and between the second lens unit and the third lens unit become wider at the telephoto position than at the wide-angle position, and the third lens unit remains fixed. Thus, a telephoto zoom lens which has a large aperture and in which aberrations extending from infinity to a short distance are favorably corrected can be provided.

    摘要： A real image mode variable magnification finder includes an objective system having a positive refracting power, an image erecting optical system for erecting an image formed by the objective system, and an eyepiece system having a positive refracting power. The objective system is composed of a first lens unit of a negative biconcave lens, a second lens unit of a positive lens, and a third lens unit of a positive meniscus lens with a convex surface directed toward the image side. The first lens unit is fixed and the second and third lens units are moved along the optical axis, thereby changing the magnification of the finder. In this way, the real image mode variable magnification finder of wide-angle design can be provided which is compact in size, has a high variable magnification ratio, and exhibits excellent performance for correction for aberration.

    摘要： The invention provides a high-performance objective lens that is capable of implementing focusing relative to an object point distance change with no or little angle-of-view change, and is well compatible with a high-pixel type imaging device. The objective optical system comprises, in order from an object side thereof, a first group of negative power, a second group of positive power, an aperture stop, and a third group of positive power. Only the second group moves thereby implementing focusing relative to an object point distance change, with satisfaction of the following conditions (1)-1, (1)-2 and (8): ωf>60  (1)-1 ωn>60  (1)-2 −1.2
