Abstract
A volume diffractive optical element (E) comprising: a carrier (1) having an optical relief pattern (P) on at least one surface thereof, and at least one optically functional layer (2) applied over or onto at least one or more portions or relief features (P) of the relief pattern on the carrier (1); wherein in embodiments the at least one optically functional layer (2) comprises a plurality of discrete bodies, beads or globules (2) of optical material applied over or onto the respective individual relief portions or relief features or relief elements (P) of the relief pattern on the carrier (1).
Claims16
A volume optical element comprising:
- a carrier having a diffractive optical relief pattern on at least one surface thereof, the diffractive optical relief pattern comprising a plurality of diffractive optical relief features, and
- at least one optically functional layer applied over or onto at least one or more portions of the diffractive optical relief pattern on the carrier, and
- wherein the at least one optically functional layer comprises a plurality of discrete bodies, beads or globules of optically functional material, and respective individual ones of the said bodies, beads or globules are located over or on respective individual ones of the said diffractive optical relief features of the relief pattern on the carrier, and
- wherein the plurality of bodies, beads or globules of optically functional material forming the at least one optically functional layer are substantially separate or spaced from each other, whereby the at least one optically functional layer is substantially discontinuous over one or more portions, regions or areas of the relief pattern on the carrier.
A method for the production of a volume optical element, the method comprising:
- providing a carrier having a diffractive optical relief pattern on at least one surface thereof, the diffractive optical relief pattern comprising a plurality of diffractive optical relief features, and
- applying over or onto at least one or more portions of the diffractive optical relief pattern on the carrier at least one optically functional layer,
- wherein the at least one optically functional layer is applied in the form of a plurality of discrete bodies, beads or globules of optically functional material, and respective individual ones of the said bodies, beads or globules are applied over or onto respective individual ones of the said diffractive optical relief features of the relief pattern on the carrier so as to be substantially separate or spaced from each other, whereby the at least one optically functional layer is substantially discontinuous over one or more portions, regions or areas of the relief pattern on the carrier.
