摘要： In a zoom lens system dividable into a zooming lens component which varies the magnification without moving the image plane and a relay lens component, at least a part of the relay lens component is made to have no power so that the axial movement thereof may not vary the focal length of the zoom lens system and is moved along the optical axis in association with the zooming lens component to compensate the fluctuation of aberration caused by the movement of the zooming lens component.

摘要： A mechanical compensation type zoom lens system capable of improving performances of large diameter lenses, wide angle lenses and highly variable magnification zoom lenses. This zoom lens system comprises a convergent lens group fixed during zooming, movable lens groups for zooming and an image-forming lens group. The movable lens groups comprise three groups including a first movable divergent lens group, a second movable convergent lens group and a third movable convergent lens group as arranged in the forward order. In the movable lens groups, an interval between the second movable convergent lens group and the third movable convergent lens group is increased on the wide angle side, whereby the movement value of the first movable divergent lens group is decreased. As the result, an entrance pupil position on the wide angle side is hardly changed, so that the distortional aberration can be corrected.
摘要翻译：一种能够改善大直径透镜，广角镜头和高度可变倍率变焦镜头的性能的机械补偿型变焦镜头系统。该变焦透镜系统包括在变焦期间固定的会聚透镜组，用于变焦的可移动透镜组和成像透镜组。可移动透镜组包括按照正向顺序布置的第一可移动发散透镜组，第二可移动会聚透镜组和第三可移动会聚透镜组三组。在可动透镜组中，第二可动会聚透镜组与第三可动会聚透镜组之间的间隔在广角侧增加，由此第一可移动发散透镜组的移动值减小。结果，广角侧的入射光瞳位置几乎不变化，从而可以校正失真像差。

摘要： A zoom lens system having a wide angle of view, a large diameter and a large zooming ratio in which the distortion is well corrected. The zoom lens system includes a movable lens group and a fixed lens group for zooming. A relay lens is provided behind the zooming lens group. A compensating lens having a small refractive power is inserted between the movable lens group and the fixed lens group and is moved in association with the zooming operation. The compensating lens consists of an aspherical lens of small refractive power or a group of spherical lenses having a small refractive power as a whole. The compensating lens is located at a position between the movable lens group and the fixed lens group where the light flux advancing along the optical axis of the zoom lens system converges to the image side.

摘要： A holographic endoscope transmits light to an object and receives and transmits the image of that object. The light transmitted is used to illuminate an object with one of two beams which are derived from a single laser, while the image received is transmitted from the object. The light from the image transmitted passes through a field lens, and a second beam or reference beam is made to interfere with this light. The resulting interference pattern is recorded on a photographic plate, forming the hologram.
