Ultraviolet Nanoimprint Lithography for Fabricating Fresnel Lens
In view of the drawbacks of Fresnel lens in the traditional condenser optical system,which needs high cost and the light intensity distribution is uneven,a method of fabricating Fresnel lens by ultraviolet nanoimprint lithography is put forward.The mold of Fresnel lens is designed through ray-tracing theory of geometrical optics.The mold is imprinted by the ultraviolet nanoimprint lithography system.And after employing UV light to cure the resin,the ultra-thin Fresnel lens is fabricated.The optical properties of the ultra-thin Fresnel lens on are tested and analyzed in the sunshine.And the results show that the Fresnel lens which has low cost,high concentration and even light intensity destribution can be realized.
