    • 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.
    • 用于以期望的倍率观察样品的图像的显微镜系统包括具有远心的物镜侧表面的第一物镜,聚焦透镜,设置在从第一物镜行进的光线穿过的光路中,用于聚焦 并且形成样本图像和具有与第一物镜不同的放大倍数的第二物镜。 交换构件保持第一物镜和第二物镜,并且用于将第一和第二物镜之一放置在样品和聚焦透镜之间的观察光路中。 假定D为与样品的表面和物镜的附着面之间的距离等于被聚焦透镜的焦距的fI的准焦距,则满足不等式0.29
