Achromatic performance of different single lenses and multilayer lenses. (A) Schematic of the designer 3D-printed multilayer achromatic metalens (MAM). (B) Schematic of traditional and flat optics ...

We saw much more detail last week into European research consortium (they are here) IMEC’s 32 nm platform. One of the most revealing looks was into the tangle of decisions surrounding lithography for ...

The term high-contrast transmitarrays (HCTAs) is used when they are designed for large transmission. Low numerical aperture (NA) lenses based on HCTA have been recently reported 26,27.

Dipole scatterers for absolute characterization of high numerical aperture optics Peer-Reviewed Publication. Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS ...

The Airy disk consists of a central bright spot surrounded by concentric rings of decreasing intensity. The size of the Airy disk depends on the wavelength of the light (λ) and the numerical aperture ...

P ut simply, the ‘aperture’ is the hole in the lens that lets the light through, and for a long time camera lenses have had adjustable apertures so that you can control the amount of light. It ...
