Abstract
A refractive lens element (16) with a very thin edge thickness is mounted to withstand gun shock loads by utilizing a cell cradle (14) that is contoured to conform to the lens element surface profile (24). The lens is employed in a system having a rectangular clear aperture (26) which when projected on the circular lens defines four lens segments (36a-36d) outside of the clear aperture. The cell cradle has an opening (26) conforming to the clear aperture and carries a compliant padding (40) coextensive with the lens segments outside of the clear aperture to support the lens axially. The lens perimetrical edge (20) is bonded to the cell with a compliant bond material (44) to secure the lens in a radially symmetric position.
