Title:
DIFFRACTION OPTICAL ELEMENT AND METHOD AND DEVICE FOR PRODUCING DIFFRACTION OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/050308
Kind Code:
A1
Abstract:
A diffraction optical element (E) provided with a polymer material layer (20), wherein: the polymer material layer (20) comprises a polymer material and a pigment, said pigment being dispersed in the polymer material layer (20) or covalently bonded to the polymer material in the polymer material layer (20); and a diffraction optical element pattern configured of dot-shaped openings (concave portions (31)) and/or convex portions is arranged at the interface of the polymer material layer (20). To produce the diffraction optical element (E), the interface of the polymer material layer (20) is deformed by irradiating the neighborhood of the interface with a laser light having a wavelength that is absorbed by the pigment, and the irradiation is conducted at the interface in a preset pattern so as to form the dot-shaped openings and/or convex portions constituting the diffraction optical element pattern at the interface.
