Practical Alignment Using an Autostigmatic Microscope (ABSTRACT)
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.

What is a Point Source Microscope? (ABSTRACT)
ABSTRACT: As opposed to a bright field, reflecting microscope that produces an image of a microscopic object, a point source, or autostigmatic, microscope uses pinhole illumination to produce a diffration limited spot at the objective focus and that spot diverges as a nearly perfect spherical wavefront. This note describes many useful applications of the Point Source Microscope (PSM), a modern version of the classic autostigmatic microscope, that also includes a bright field imaging option and is useful as an autocollimator.
