ABSTRACT:
One or more optical slits of a variable optical slit assembly limit the widths of optical beams propagating through the optical slits. A frame assembly of the variable optical slit assembly operatively couples one or more encoded translators to the optical slits. In operation, rotations of the encoded translators alter the widths and/or positions of the optical slits.
