ABSTRACT:
A field adjustable beam splitter includes a mirror pivotably supported at a pivot point, a first wedge which is movable and which supports the mirror at a first support point, and a second wedge which is also movable and which supports a mirror at a second support point. The support points and pivot points are preferably arranged in a right triangular relationship with the pivot point being at the right angled apex thereof. Motion of the wedges along parallel paths of travel causes the mirror to tilt on its pivot axis in mutually perpendicular directions.
