Abstract
Method and apparatus for optically aligning, for subsequent assembly into discrete packages, opto-mechanical components, e.g., optical filters, and lenses for directing direct light to and from those opto-mechanical components. The apparatus comprises a light source for producing a beam of light emulating the light which exists in the assembled package of components during use, manipulator means for supporting a lens and a selected opto-mechanical component in tandem along the optical axis of the light beam and for moving the lens and selected opto-mechanical component along X and Y axes perpendicular to that optical axis, and a machine vision system having imaging means for recording images of the light beam and the opto-mechanical component and being adapted to control operation of the manipulator means so as to cause the latter to shift the lens and opto-mechanical component along the X and/or Y axes to achieve optical alignment.
