Abstract
This paper discusses the causes of lenses decentration at their gluing in the frame. We give the dependences of displacement value of the centers of curvature for the lens working surfaces from the base frame axis on the primary technological errors of interfaced details. It is shown that some errors of form and position of the frame surfaces produce an effect not on the accuracy of the lenses centering in the frame, but on the accuracy control centering. That causes displacement of the lens working surfaces centers when assembling the lens unit into the objective body. A functional diagram of the station for automated gluing and centering of lenses in the frames is shown; the accuracy of its work is considered. We present the ways of accuracy improvement of lenses centering in the frames carried out on this station, thanks to the centering along not one, but two working surfaces of the lens. The design of composite frames has been developed for performing exact centering of lenses at assembly for the various options of their deployment in the frames. Modernization of technological process for the lens automated alignment has been performed to implement centering along both working surfaces.

Keywords: lenses, frames, centering, decentration, alignment.
