Materials scientists have recently attempted to achieve achromatic lenses to uncover a tradeoff between the numerical aperture and bandwidth that limits the performance of such materials.

used and the resolving power of the microscope objective, defined by its numerical aperture (NA), with the maximum value of NA = 1 for an objective in air. The resolution limit, which defines the ...

and achieves high numerical aperture *2 and high resolution. Higher resolution images up to the periphery of the field of view can be acquired when combined with the "Digital Sight 10" microscope ...

Led by Professor Peter Banzer, they propose and implement a novel technique for an absolute characterization of high numerical aperture microscope objectives, working without an aberration-less or ...

We present an oblique plane microscope (OPM) that uses a bespoke glass-tipped tertiary objective to improve the resolution, field of view, and usability over previous variants. Owing to its high ...

This paper performs a numerical study of the imaging process in confocal microscopy. We simulate the imaging result using Fresnel diffraction formula. We also consider the divided aperture technique ...

The magnitude of diffraction and, hence, the resolving power of an optical microscope depends on the light wavelength (λ) and the numerical aperture (NA) of the objective lens. As a result ...

Typically, Muller said, the resolution of an electron microscope is dependent in large part on the numerical aperture of the lens. In a basic camera, numerical aperture is the reciprocal of the ...
