An optical lens stack includes an inner ring of a mounting structure containing axially spaced circumferential lens mounting surfaces on an inside diameter of the inner ring. The inner ring further includes a groove over a fixed axial length on the outer diameter. An outer ring formed to fit over the inner ring contains a groove on the inner diameter of the outer ring that corresponds to the groove on the inner ring and forms a circumferential cavity when the outer ring is mounted on the inner ring. The resulting cavity is filled with an energy absorbing material and serves as a vibration isolator for the lens stack.
