Multifocal spectral diffractive lens [PDF]
Компьютерная оптика, 2018 We present a method for calculating a spectral multifocal diffractive lens that forms a given set of fixed-position foci at multiple operating wavelengths. It is based on minimizing a function represented as a squared absolute value of difference between

Multivariate Techniques for Identifying Diffractive Interactions at the LHC [PDF]
, 2009 Close to one half of the LHC events are expected to be due to elastic or inelastic diffractive scattering. Still, predictions based on extrapolations of experimental data at lower energies differ by large factors in estimating the relative rate of ...

ADVANTAGES OF DIFFRACTIVE OPTICAL ELEMENTS APPLICATION IN SIMPLE OPTICAL IMAGING SYSTEMS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2015 The paper deals with the influence of diffractive optical elements on the optical aberrations. The correction of optical aberrations was investigated in the simple optical systems with one and two lenses (singlet and doublet).

Longitudinal component of the Poynting vector of a tightly focused optical vortex with circular polarization [PDF]
Компьютерная оптика, 2018 We numerically investigated the focusing of optical vortices with the wavelength λ = 532 nm and right-hand circular polarization by using a diffractive lens with the numerical aperture NA = 0.95.

Calculation of a diffractive lens having a fixed focal position at several prescribed wavelengths [PDF]
Компьютерная оптика, 2019 A method for calculating a “spectral” diffractive lens, which ensures the preservation of the focal position at several prescribed wavelengths is proposed.

Diffractive properties of the Diffrax bifocal lens
, 1993 We have verified that the Pilkington Diffrax lens behaves optically as a diffractive bifocal contact lens. The longitudinal chromatic aberration of the lens is similar of that predicted by theory, both on and off the eye.
