High numerical aperture multilayer Laue lenses
The ever-increasing brightness of synchrotron radiation sources demands improved X-ray optics to utilise their capability for imaging and probing biological cells, nanodevices, and functional matter on the nanometer scale with chemical sensitivity. Here we demonstrate focusing a hard X-ray beam to an 8 nm focus using a volume zone plate (also referred to as a wedged multilayer Laue lens). This ...

متن کاملHigh-resolution microscopy without high-numerical-aperture lenses: standing-wave scanning fluorescence microscopy
We propose and demonstrate a new type of far-field fluorescence microscope capable of sub-λ resolution without high numerical aperture (NA) lenses. In the new standing-wave scanning fluorescence microscope, focused illumination is generated by the interference of a large number of planar wavefronts. Scanning confocal detection eliminates the need for modulation of wavefront phases during image ...
متن کاملPlanar high-numerical-aperture low-loss focusing reflectors and lenses using subwavelength high contrast gratings.
We propose planar, high numerical aperture (NA), low loss, focusing reflectors and lenses using subwavelength high contrast gratings (HCGs). By designing the reflectance and the phase of non-periodic HCGs, both focusing reflectors and lenses can be constructed. Numerical aperture values as high as 0.81 and 0.96 are achieved for a reflector and lens with very low losses of 0.3 and 0.2 dB, respec...
متن کاملQuantitative x-ray phase imaging at the nanoscale by multilayer Laue lenses
For scanning x-ray microscopy, many attempts have been made to image the phase contrast based on a concept of the beam being deflected by a specimen, the so-called differential phase contrast imaging (DPC). Despite the successful demonstration in a number of representative cases at moderate spatial resolutions, these methods suffer from various limitations that preclude applications of DPC for ...
