Centering of optical components by using stick-slip effect

Abstract

Centering of optical lenses is necessary for obtaining the required resolution of an optical system, especially minimization of distortion. Advantage is the systematic approximation of a minimized centering error of the individual lens in relation to its housing. A method by using stick-slip effect has been developed. The process has an automatic numerical control which operates during rotation ofthe lens. The adjustment tool is driven by electro-magnetic hammers in a step-by-step mode.

Precise adjustment method using stroke impulse and friction

“…An exceptional application for precise aligning of mounted lenses being in motion is a CNC-lathe with a centering and special measurement device [4]. The production process splits into three steps.…”
