The simplest DOE profile is binary: two profile planes produce the required phase shift of the light. Multi-stage profiles with a single grating period allow for more precise phase control.

The combination of writing process, development process and etching process at ZEISS delivers precise results with very low roughness. These low-scatter, diffractive, optical elements with sub-nanometer roughness baseline are beneficial in certain applications.

Opticalcomponents examples

Diffractive optical elements (DOE) diffract light at the microstructured surface. Thanks to their high level of functionality, several optical functions can be integrated simultaneously in a single element. DOEs thus enable very compact, lightweight and elegant practical solutions, which with purely refractive macro optics, are only possible at a very high cost.

From regular periodic micro-lens arrays to randomized continuous phase profiles, Advanced Optical Technologies, Band 4, Heft 1, Seiten 47–61, eISSN 2192-8584, ISSN 2192-8576, DOI: https://doi.org/10.1515/aot-2014-0062

Diffractive optical elements (DOEs) are optical components that deflect light into multiple orders at precise angles. Periodicity and their spatial frequencies, rather than the surface topography profile, determine the optical performance.
