Abstract

PURPOSE:To perform an optical path changing, by sliding an optical system element in which a Pechan-Dach prism is installed behind the objective lense, in a plane normal to the optical sxis. CONSTITUTION:A laser beam generated by a laser beam source device 1 is irradiated upon an objective lense 2 and becomes a convergent light. A Pechan-Dach preism 3 is installed behind the objective lense 2 so that it may be moved for a minute distance in the plane normal to the optical axis in response to the movement of a fine adjustment 6. When the Pechan-Dach prism 3 is moved with the fine adjustment 6, a convergent portion 5 by the objective lense 2 moves to a location 5' due to the optical characteristic of the prism 3. That is to say, a required continuous movement of convergent portion 5 can be obtained by moving the prism only instead of moving the whole apparatus, and required working can be performed.
