1. A convertible optical system comprising:
a baseplate having a face, the baseplate including:
one or more recesses formed in the face of the baseplate, each of the one or more recesses adapted to locate one or more corresponding first optical element stages;
one or more pedestals formed in the face of the baseplate, each of the one or more pedestals adapted to locate one or more corresponding second optical element stages;
a first plurality of threaded holes, each of the first plurality of threaded holes adapted to receive a corresponding mounting bolt for a corresponding one of the first or second optical element stages;
a second plurality of holes, each of the second plurality of holes adapted to receive a corresponding guide pin for a corresponding one of the first or second optical element stages;
wherein a corresponding elevation of each of the one or more recesses and each of the one or more pedestals is adapted to place an optical axis of each optical element mounted to a corresponding one of the first or second optical element stages in a common plane, the common plane being parallel to the face of the baseplate; and
wherein the one or more recesses, the one or more pedestals, the first plurality of threaded holes, and the second plurality of holes are adapted to permit the convertible optical system to form at least two of a single pass optical system, a double pass optical system, a single pass/double pass optical system, or a double pass/single pass optical system.
