Lens holding method and lens holder

摘要

A lens element, that is guided along a tapered wall of a lens holder and slipped into the lens holder, is fixedly held on a lens support collar at a bottom of the lens holder by thermally deforming fixing claws of the lens holder so as to grasp the outer periphery of the lens element. The fixing claws are arranged in diametrically symmetrical positions with respect to a center axis of the lens holder so as to align the optical axis of the lens element and the center axis of the lens holder.
