Optical performance of holographic kinoforms
WebFeb 1, 2024 · The diffraction‐limited focus of a UV femtosecond laser is scanned in a photoresist composed of only a monomer to print X‐ray optics called kinoforms. This … WebThe optical properties of holographic kinoforms are described. It is shown that paraxial designs are not adequate for f-numbers less than approximately F/10. A non-paraxial design is introduced which retains the high diffraction efficiency of the paraxial designs, yet also produces a non-aberrated diffracted wavefront for the design wavelength. Aberration …

WebJan 18, 2010 · This method provides an efficient and reliable way of generating rotationally symmetric free form optical surfaces that are otherwise difficult to produce with conventional methods such as lithography and etching methods.
WebSeveral design-concepts are presented for so-called efficiency achromatized diffractive optical elements (EA-DOEs) possessing diffraction efficiency larger than 97% over a broad spectral range. We start with tracing two different methods for surface relief profiles well known from the literature: common depth and multilayer EA-DOEs. WebApr 20, 2024 · The enhanced-NA Fresnel hologram reconstructs a holographic image at a viewing angle larger than the diffraction angle of a hologram pixel. The image space is limited by the bandwidth of a digital hologram. In this study, we investigate the property of image formation in the extended image space beyond a diffraction zone. A numerical …
