“…18 The energy distribution between the orders is determined by the particular form of this function. Thus, the complex amplitude of the beam transmitted through the multifocal lens can be represented as the following superposition of spherical beams: 5,17 WðρÞ ¼ ffiffiffiffiffiffiffiffiffiffi ffi…”

“…18 Thus, to form an energy distribution I m , m ¼ −1; 0; 1 in the corresponding foci F m , the function ΦðξÞ is determined as the phase function of a diffraction grating with period 2π and diffraction orders intensities I m , m ¼ −1; 0; 1. 17 The grating calculation can be carried out by means of the Gerchberg-Saxton algorithm or gradient methods. 18 As an example, Fig.…”

Abstract. The fabrication of submicron-height sine-like relief of a trifocal diffractive zone plate using a nanoimprinting technique is studied. The zone plate is intended for use in combined trifocal diffractive-refractive lenses and provides the possibility to form trifocal intraocular lenses with predetermined light intensity distribution between foci. The optical properties of the designed zone plate having the optical powers 3 D, 0, −3 D in the three main diffraction orders are theoretically and experimentally investigated. The results of the theoretical investigations are in good agreement with experimental measurements. The effects of the pupil size (lens diameter) as well as the wavelength-dependent behavior of the zone plate are also discussed. © The Authors.

Hybrid intraocular lenses (IOLs) are diffractive-refractive lenses with pseudoaccomodation. They can imitate the optical system of health eye more precisely, than other types. These lenses have 2-3 or more stable focuses. I proposed a comparison of hybrid IOLs: their shape, their processing, their aberrations and diffractive efficiency. I showed a review of new methods for correction of chromatism and I proposed a method of using volume holograms. I discussed features of possible materials.

“…However, we can carry out diffractive analyzes only for simple phase functions, axially symmetric illuminating beams and focus areas -such as the ring [12], a set of points [18][19][20], longitudinal [21][22][23][24] or cross [15][16][17][25][26] segments. In some cases, the analytical study can provide diffractive corrections to the phase function of focusator [14].…”
