An optical device is produced by (a) providing an optical element; (b) providing a photopolymerizable composition comprising (i) a photopolymerizable monomer or oligomer, or a mixture thereof, capable of forming a polymer having predetermined optical properties, (ii) a photoinitiator sensitive to near infrared radiation, and (iii) a filler having optical properties selected to contrast with the optical properties of the polymer; (c) applying a layer of the photopolymerizable composition onto the optical element; and (d) exposing the optical element with the layer of photopolymerizable composition thereon to near infrared radiation to cause polymerization of the monomer or oligomer, or mixture thereof, and formation of a recording pattern on the optical element, the recording pattern comprising areas having different densities of filler in exposed and unexposed areas of the layer, thereby obtaining an optical device having thereon areas with different optical properties.
