Abstract
An apparatus and method for housing an optical element are provided. A ring is configured with a symmetry that corresponds to that of the optical element and for bonding with the optical element on an optical surface at a periphery of the optical element. An axial retaining spring may be provided for securing the optical element within an optical-system assembly. The axial retaining spring includes axial constraint fingers to engage a subsequent optical component and structures adapted to apply a point load at selected locations on the optical element.
