Simple method of aligning cylindrical air-spaced elements

Paper Abstract

A simple method is found to align multielement cylindrical lenses. The method employs only equipment found in most optical shops: a precision flat mirror and a Fizeau interferometer. A combination of narrow reflection interferograms from the lens surfaces, combined with cat-eye double-pass interferograms, is employed to align the elements.
