Abstract
PURPOSE: To realize the reduction in size and manufacturing at the cheaper cost by properly aligning the moving direction of a corner cube and the incident direction of a light beam from a light source.
CONSTITUTION: A corner cube 4 is disposed in such orientation that a light beam emitted from a light source 1 after having passed a half mirror 2 enters the corner cube 4 straightly. The moving direction of the corner cube 4 is set in parallel to the light beam emitted from the light source 1 and entering the corner cube 4 straightly. A light beam having passed through a condensing lens L is bent by a plane mirror 6, so that the light beam emitted from the light source 1 enters a measured lense system Lex in parallel to the moving direction of the corner cube 4. Further, the corner cube 4 and the measured lense system Lex are positioned at the opposite side of the half mirror 2 with respect to the condensing lense L.
