Numerical modelling of MLLs has been carried out using methods such as coupled wave theory, the beam propagation method (equivalent to the multislice technique) and dynamical diffraction of distorted ...

Flat optics are made of nanostructures containing high-refractive index materials to produce lenses with thin form factors that function only at specific wavelengths. Materials scientists have ...

Flat optics have attracted interest for decades due to their flexibility in manipulating optical wave properties, which allows the miniaturization of bulky optical assemblies into integrated planar ...

Researchers have designed an optical lens with the highest free-space numerical aperture to date, achieving a value of just under 1. As the numerical aperture indicates the highest possible resolution ...

Designed with new manufacturing technology that creates lenses with shapes that are difficult to fabricate using other methods, Olympus’ new X Line™ series objectives and the UPLAPO-HR objectives for ...
