Abstract:
Spectral and angular dependences of the diffraction efficiency of two-layer single-relief sawtooth microstructures are analyzed. The microstructures are assembled from optical plastics and new brands of special optical glass. This makes it easy to replicate elements with diffraction microrelief by precision casting or stamping. Wide possibilities of weakening the dependence of the diffraction efficiency of such microstructures on the wavelength and the angle of incidence of radiation on the element are demonstrated.

Keywords:
diffraction efficiency, diffractive optical element, relief-phase diffraction microstructure, scalar and rigorous diffraction theories.
