Patent number: 8659825Abstract: An apparatus adapted to a microscope includes a body, a revolvable structure, a stage and a driving device. The body has a slot for holding a liquid to form a horizontally level surface of the liquid. The revolvable structure partially accommodated within the slot and pivotally connected to the body is revolvable relative to the body about a horizontal axis and is for supporting a sample, which is immersed in the liquid. The revolvable structure penetrates through the body in a horizontal direction substantially parallel to the horizontal axis and is pivotally engaged to the body through a sealing ring, which makes the liquid be held in the slot and stops the liquid from leaking in the horizontal direction. The stage supports the body. The driving device is disposed on the stage and connected to the revolvable structure to revolve the revolvable structure.Type: GrantFiled: November 5, 2012Date of Patent: February 25, 2014Assignee: National Tsing Hua UniversityInventors: Chien-Chung Fu, Hsiu-Ming Chang, Ann-Shyn Chiang
