    • PROBLEM TO BE SOLVED: To provide a retention mechanism for an immersion objective lens or an immersion medium, which is configured such that when a specimen is observed and measured, the immersion medium supplied to the tip of an objective lens is hindered from dripping from the tip of the objective lens even if the measurement involves a large amount of movement and takes a long time, and also to provide a method of manufacturing the same. SOLUTION: The retention mechanism for the immersion medium includes: an immersion objective lens 10; a bottom plate 41 with an opening for engaging with the immersion objective lens; a wall 42 disposed around the bottom plate 41; an immersion medium supply section 34 for supplying an immersion medium to the tip of the objective lens; and a droplet discharge part 35 which is disposed near the wall of the bottom plate and discharges a droplet of the immersion medium from the tip of the objective lens. The bottom plate has a first ring member (α portion ) made of a first material for holding the immersion medium, which is disposed so as to surround the opening. The bottom plate inclines so that the opening side is higher than the wall side. The affinity of the first ring member with the immersion medium is lower than that of an inside member of the first ring member with it. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:为了提供一种浸没物镜或浸没介质的保持机构,其被配置为使得当观察和测量样本时,供应到物镜的尖端的浸没介质被阻止 即使测量涉及大量运动并且需要很长时间,也从物镜的尖端滴下,并且还提供其制造方法。 浸渍介质的保持机构包括:浸没物镜10; 具有用于与浸没物镜接合的开口的底板41; 围绕底板41设置的壁42; 浸没介质供给部34,用于将浸没介质供给到物镜的前端; 以及液滴排出部35,其设置在底板的壁附近,并从物镜的前端排出浸没介质的液滴。 底板具有由用于保持浸没介质的第一材料制成的第一环构件(α部分),该第一环构件围绕开口设置。 底板倾斜使开口侧高于壁面。 第一环构件与浸渍介质的亲合力低于第一环构件与浸没介质的内部构件的亲和性。 版权所有(C)2010,JPO&INPIT
