The key contribution is the design, analysis, and fabrication of a dual-element off-axis magnifier to improve the state of the art in catadioptric magnifiers. The catadioptric magnifier is composed of a free-form mirror and a lens with a diffractive optical element. A monocular magnifier was prototyped, to our knowledge for the first time, with the specifications of an 8 mm exit pupil, 20 degre...

We report on the changes in the spectrum of a femtosecond pulse originated by diffraction of the ultrashort waveform through a circularly symmetric binary diffractive optical element. The analysis is performed in the framework of the Rayleigh-Sommerfeld formulation of the diffraction, where an analytical expression for the monochromatic amplitude distribution close to the optical axis is obtain...

We perform a comprehensive theoretical assessment of fabrication tolerances for a 2D eight-level binary phase grating that is the central element of a multi-focal plane 3D microscopy apparatus. The fabrication process encompasses a sequence of aligned lithography and etching steps with stringent requirements on layer-to-layer overlay, etch depth and etched sidewall slope, which we show are none...

Optical design and fabrication techniques are crucial for making optical elements. From conventional lenses to diffractive optical elements and to recent metasurfaces, various types of optical elements have been proposed to manipulate light where optical materials are fabricated into desired structures. Here, we propose a scattering optical element (SOE) that exploits multiple light scattering ...

The energy and spectral conditions for single-stage holographic recording of a diffraction optical element based on the carbazole-containing azo polymer, that forms singular light beams (optical vortices), have been established. With atomic-force microscopy (AFM), surface morphology recorded relief holograms was studying, their efficiency has estimated. topology generated phase singularities st...

Light sheet fluorescence microscope with single light illumination enables rapid 3D imaging of living cells. In this paper we show the design, fabrication and characterization a diffractive optical element producing several sheets along 45° inclined tube. The element, which is based on multi-focal lens linear grating, generates five thin equal intensities when combined refractive cylindrical le...

The projection lens is the core component of DMD-based maskless lithography and its imaging quality directly affects transferal exposure pattern. Based on traditional system, we have designed diffractive optical element (DOE) aspheric surfaces to optimize refractive/diffractive hybrid system improve quality. We found that best effect obtained when DOE very close front group before diaphragm sys...

Far-Field Super-Resolution Microscopy In article number 2200307, Qiaofeng Tan and colleagues propose a high-fidelity far-field microscopy with spatial resolution at λ/8. Assisted by two-dimensional multi-level diffractive optical element, the efficiency least increases two orders in contrast to reported superoscillatory, which ensures of 69 nm for complex samples high-fidelity.
