ABSTRACT: This paper defines optical alignment as placing optical conjugates and centers of curvature at the precise locations specified in the optical design. Auto-stigmatic microscopes (ASM) are the tools used to measure the offset between the optical conjugates and physical datums such as centers of balls and axes of cylinders in alignment fixtures and making precise alignment practical.
