  • Patent number: 4854671
    Abstract: A mount for an optical element such as a lens element wherein the optical element has a cylindrical circumferential rim and at least three ribs formed of a material having a highly elastic property. The ribs have a predetermined length and are disposed at a predetermined distance from one another along the cylindrical circumferential rim of the optical element with each rib having an inner periphery in continuous contact with an outer periphery of the cylindrical circumferential rim of the optical element. The ribs are compressed on assembly of the optical element into the mount so that centration of an optical system, e.g., the lens, is substantially improved.
