Ray Tracing Methods for Correcting Chromatic Aberrations in Imaging Systems
The correction of chromatic aberrations is typically performed using aberration formulas or by using real ray tracing. While the use of aberration formulas might be effective for some simple optical systems, it has limitations for complex and fast ...

Multiwavelength polarization insensitive lenses based on dielectric metasurfaces with meta-molecules [PDF]
Metasurfaces are nano-structured devices composed of arrays of subwavelength scatterers (or meta-atoms) that manipulate the wavefront, polarization, or intensity of light.

PURPOSE Most optical systems present chromatic aberration quantified along the optical axis by the longitudinal chromatic aberration (LCA). LCA is controlled by the biomaterial Abbe number combined with diffractive effects, driven by the intraocular lens

Multimodal label-free ex vivo imaging using a dual-wavelength microscope with axial chromatic aberration compensation [PDF]
. Label-free microscopy is a very powerful technique that can be applied to study samples with no need for exogenous fluorescent probes, keeping the main benefits of multiphoton microscopy, such as longer penetration depths and intrinsic optical ...

Achromatic polymer-dispersed liquid crystal lens with diffractive–refractive hybrid structure
The focal length of liquid crystal Fresnel lens is electrically controllable, but the disadvantage is the chromatic aberration is obvious. In this paper, the electrically controlled zoom characteristics of liquid crystal lens and the basic theory of ...

Broadband achromatic optical metasurface devices
Metasurfaces suffer from large chromatic aberration due to the high phase dispersion of their building blocks, limiting their applications. Here, Wang et al. design achromatic metasurface devices which eliminate the chromatic aberration over a continuous
