摘要
A metal ring for an optical element that is served to cover a peripheral side surface of a lens and served to fix the lens to a mounting member by means of soldering is provided with a thin-wall sleeve a diameter of which is expanded toward a peripheral direction by means of pressure received from an optical material disposed inside the metal ring to thereby obtain a final peripheral side surface size, a thin-wall portion having an inside periphery near an extension of an inside peripheral surface of the thin-wall sleeve on one of apertures of the thin-wall sleeve, and a holding portion comprising a flange that projects from an edge of the aperture toward the aperture. A metal ring for an optical element, a method for fabrication of the optical element having the metal ring, and an optical element having a metal ring of the invention employ the abovementioned metal ring.
