Abstract

A diffractive optical element is provided, which includes a first layer having a material of a refractive index n1(λ), a second layer, adjacent to the first layer, having a material of a refractive index n2(λ) and a diffraction structure formed at the interface between the first layer and the second layer. The material of at least one of the two layers is obtained by curing an optical adhesive.
