An optical assembly (30; 130) comprises a mounting structure (32; 132), a plurality of optical elements (34; 134), and a conformal filler material (54; 154). The mounting structure (32; 132) has a plurality of axially spaced circumferentially recessed undercuts (44; 144) formed into an inner surface (42; 142) of the mounting structure (32; 132). The optical elements (34; 134) are axially spaced in the mounting structure (32; 132). At least one of the optical elements (34; 134) includes an undercut (38; 138) in a perimeter edge surface (40; 140). The undercut (38; 138) is aligned with one of the plurality of undercuts (44; 144) in the mounting structure (32; 132), such that the aligned circumferential undercuts (38; 138) define a void (48; 148). The conformal filler material (54; 154) is cast in place in the void (48; 148) to create a mechanical lock between the optical element (34; 134) and mounting structure (32; 132).
