Abstract (en)
[origin: WO2009056196A1] Specified is a diffractive optical element which comprises a first layer (12) made of a material with a refractive index ni(?), a second layer (14) which adjoins the first layer (12) and is made of a material with a refractive index n2(?), and a diffractive structure (18) formed on the boundary area (16) between the first layer (12) and the second layer (14). The material of at least one of the two layers (12, 14) is obtained by curing an optical adhesive. Furthermore specified is the use of an optical adhesive for producing a diffractive optical element according to Claim 1.
