Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light's amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the ...

Computational microscopy is vital in biomedicine and materials science. Traditional methods struggle with optical aberrations, noise interference, and differences between physical models and ...

A computer-assisted design schematic showing how an electron beam is routed within a microscope. After going through the sample, it crosses a bright cyan beam representing the laser beam. A schematic ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside ...
