A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

This can be achieved using optical and processing tricks to increase the numerical aperture of the projection lens in the system, or by reducing the wavelength of the light used. Since the 1980s ...

The measurement of the acceptance angle of an optical fiber, which is the maximum angle at which the core of the fiber will take in light that will be contained within the core. Taken from the ...

This meant that a microscope could not resolve two objects located closer than λ/2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens. This diffraction ...

Corning has introduced its new ultra-low expansion (ULE) material that is designed to withstand ever increasing power of upcoming Low-NA (Numerical Aperture) and High-NA EUV lithography systems.

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 ...
