Abstract

A novel tip-tilt mechanism has been designed which is capable of aligning a small 1-inch optic with one arc second resolution. This mechanism performs this function without the aid of a piezoelectric device or other electronic technology. The optic is bonded to a three bipod mount in series with a spring-loaded flexure. Three manually adjustable differential screws drive the flexure. The bipod/flexure arrangement allows highly accurate and stable adjustment. This paper will give an overview of the design, and present laboratory data and analysis quantifying the adjustment resolution of the mechanism. Material and surface coating selection is also presented.
