LENS AND METHOD FOR PRODUCING A LENS

摘要

The invention relates to a rod lens (3) having one or several optically active and one or several optically inactive surfaces, whereby a part of said optically inactive surface(s) (7, 8), in particular a lens facet and/or radial peripheral surface (7) of a lens (3), is smooth. Said invention also relates to a method for smoothing a part of one or several optically inactive surfaces (7, 8) of a lens (3), in particular a lens facet and/or radial peripheral surface (7) of a lens (3). The formation of cracks in the lens (3) is thus prevented or reduced.
