Abstract
PURPOSE:To enable moving parts to be made compact, high accuracy to be expected and optical path length to be changed through simple operation by providing a pair of parallel plane reflecting mirrors, one of which is made movable along optical axis, in the optical path and maintaining parallel even after moving.
