摘要： A microscope system for observing an image of a sample at desired magnifications includes a first objective lens having an objective side surface which is telecentric, a focusing lens, disposed in an optical path along which optical rays emitted from the first objective lens travel, for focusing the optical rays and forming a sample image and a second objective lens having a magnification factor different from that of the first objective lens. An interchanging member holds the first objective lens and the second objective lens and is used for placing one of the first and second objective lenses in an observational optical path between the sample and the focusing lens. The inequality 0.29 is satisfied, assuming D to be a parfocal length which equals a distance between a surface of the sample and an attachment plane of the objective lens and fI to be a focal length of the focusing lens.

摘要： The goal of the disclosed invention is to obtain a condenser lens system which is applicable to illumination conditions of objective lenses with super-wide fields of view in a range between 1x and 100x. The condenser lens system consists of, between the light source and the surface of the illuminated object: a first lens group which has negative refractive power, a second lens group which has positive refractive power, and a third lens group which has positive refractive power. The first and third lens groups are separately movable to an application position which is located on the optical axis, and the removed position, which is located outside the optical axis. When using a high-magnification objective lens of the microscope, the first lens group is placed at the removed position and the third lens group is placed at the application position so that the condenser lens system as a whole has a positive refractive power. When using a low-magnification objective lens, the first lens group is placed at the application position and the third lens group is placed at the removed position so that the condenser lens system as a whole is substantially an afocal system.
摘要翻译：所公开的发明的目的是获得一种聚光透镜系统，该系统适用于具有超宽视野范围内的1x和100x之间的物镜的照明条件。聚光透镜系统由光源和被照射物体的表面之间组成：具有负折光力的第一透镜组，具有正折射光焦度的第二透镜组和具有正屈光力的第三透镜组。第一和第三透镜组可分别移动到位于光轴上的施加位置和位于光轴外部的移除位置。当使用显微镜的高倍率物镜时，将第一透镜组放置在去除位置，并且将第三透镜组放置在施加位置，使得聚光透镜系统整体具有正折射力。当使用低倍率物镜时，第一透镜组被放置在施加位置，并且第三透镜组被放置在去除位置，使得聚光透镜系统整体上基本上是无焦点系统。
