Such solid lenses or mirrors are designed under the assumption that their surfaces are formed from a set of 100 concentric spherical rings. The values of the curvature radii of each ring are different and optimum values are calculated with Genetic Algorithms (see Appendix A). Hence, this set ...
We report on creating a module for the Geant4 toolkit for a simulation of point-by-point defined Fresnel lenses and mirrors. This module provides creation of cylindrical Geant4 shapes with one or two Fresnel surfaces, defined by the arrays of points ( z (ρ))....

security cameras. The high-end tele-zoom lenses offer optical image stabilization, autofocus function, a visible light cut filter, neutral density filters, a built-in 2× extender and many more features for highest image quality. Analog control is provided as well as a serial...See full ...
Called multilayer Laue lenses (MLLs)8, these structures are fabricated by layer deposition, using technologies developed for making multilayer mirrors9. Layer periods thinner than 1 nm are achievable by magnetron sputtering10. Lenses are made by alternately depositing two (or more) materials with ...
Direct laser writing (DLW) has been shown to render 3D polymeric optical components, including lenses, beam expanders, and mirrors, with submicrometer precision. However, these printed structures are limited to the refractive index and dispersive properties of the photopolymer. Here, we present the ...

These simulators are based on adaptive optics elements (deformable mirrors or spatial light modulators [51–53]) or temporal multiplexing (e.g., SimVis technology [54–56]) and work by projecting the theoretical multifocal pattern design onto the patient´s pupil plane, allowing us to evaluate...
