A PSF-Based Approach to Biplane Calibration in 3D Super-Resolution Microscopy

Michaël Unser, Daniel Sage, Hagay Kirshner

Super-resolution localization microscopy methods such as PALM and STORM have been shown to provide imaging with resolutions up to a few tens of nanometers while using relatively simple setups. Biplane PALM has extended the PALM technique to three-dimensio ...

Subwavelength-size solid immersion lens

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the fabrication and characterization of nanoscale solid immersion lenses (nano-SILs) with sizes down to a subwavelength range. Submicrometer-scale cylinders fabricated by electron-beam lithography are thermally reflowed to form a spherical sha ...

Beyond the lateral resolution limit by phase imaging

Christian Depeursinge, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We present a theory to extend the classical Abbe resolution limit by introducing a spatially varying phase into the illumination beam of a phase imaging system. It allows measuring lateral and axial distance differences between point sources to a higher ac ...

Full-field microimaging with 8 keV X-rays achieves a spatial resolutions better than 20 nm

Giorgio Margaritondo

Fresnel zone plates (450 nm thick Au, 25 nm outermost zone width) used as objective lenses in a full field transmission reached a spatial resolution better than 20 nm and 1.5% efficiency with 8 keV photons. Zernike phase contrast was also realized without ...
