An optical assembly comprises a mounting structure, a plurality of optical elements, and a conformal filler material. The mounting structure has a plurality of axially spaced circumferentially recessed undercuts formed into an inner surface of the mounting structure. The optical elements are axially spaced in the mounting structure. At least one of the optical elements includes an undercut in a perimeter edge surface. The undercut is aligned with one of the plurality of undercuts in the mounting structure, such that the aligned circumferential undercuts define a void. The conformal filler material is cast in place in the void to create a mechanical lock between the optical element and mounting structure.
