"High-numerical aperture lenses/microscope objectives are major optical components that are widely used in microscopy, optical detection systems, optical lithography, quantum optics, etc.," ...

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 ...

Typically, Muller said, the resolution of an electron microscope depends in large part on the numerical aperture of the lens. In a basic camera, this is notated with the “f-number”—the smaller the ...

The size of the Airy disk depends on the wavelength of the light (λ) and the numerical aperture (NA) of the objective lens. The spatial resolution of the microscope is determined by the ability to ...

These high numerical aperture lenses work well in the visible spectrum as well as at 405 nm, which is the wavelength utilized to capture widefield confocal pictures. Widefield confocal technology in ...
