Microscope provided with an objective lens focusing apparatus and an objective lens switching apparatus

摘要

A rough motion shaft 54 and a fine motion shaft 55 are provided on a front side of a stage 37 with respect to an optical axis of an observation optical system of a microscope. Further, a rough motion shaft 45 and a fine motion shaft 46 are provided on a rear side with respect to the optical axis. The rough motion shaft 54 and the fine motion shaft 55 are linked with the rough motion shaft 45 and the fine motion shaft 46 so as to move objective lenses 43 selectively in rough motion or fine motion. Objective lenses 43 A, 43 B are arranged in a circular shape on a fixing member 111 and a rotating member 113 rotates objective lenses 43 A, 43 B along the direction of the arrangement. The rotating member 113 includes a weight 123 that applies a rotation force in an inverse direction.
