Abstract
There is disclosed a manufacturing method and apparatus which allows for the efficient assembly of the exposure module of a xerographic reproduction system. The system uses an array of deformable mirrors fabricated in one embodiment, on a monolithic silicon substrate as a light modulation element. The substrate package is positioned with respect to a set of molded support brackets such that a multi-axis adjustment of this single element allows for the alignment of the entire optical set. A system of cameras is used, in conjunction with a computer, to control the substrate positioning and to determine optimum efficiency of the system. The computer adjusts the package around the various rotational axis in sequential fashion.
