Centering of optical components by using stick-slip effect

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 an 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 of the lines. The adjustment tool is driven by electro-magnetic hammers in a step-by-step mode.
