Refractive optical elements
Web13. máj 2024 · Diffractive optical elements have been used in fields such as field array generation, parallel interconnection, miniature optical element integration, and the like. These applications will be illustrated in detail after describing the preparation and the theory of the diffractive optical element. WebThe refractive and the diffractive properties of planar micro-optical elements are investigated. The transition between purely refractive and purely diffractive planar microlenses is numerically simulated for the example of differently designed phase-matched Fresnel elements.
