Plan-apochromat microscope objectives set the benchmark for precise, high-resolution imaging with exceptional color accuracy. By correcting chromatic and spherical aberrations while maintaining a flat ...

High-performance nanophotonic devices require extreme depth-to-diameter ratios, which are notoriously difficult to fabricate. Towards this goal, scientists in China developed a novel technique ...

Abstract: The sub-reflectarray compensating technique is proposed for the spherical aberration compensation in this paper. A microstrip reflectarray is a low-profile, inexpensive, and easy-to-build ...

Peripheral optical quality metrics observed in patients with myopia can be detected in children with emmetropia who are at a high risk for the disorder. More myopic peripheral retinal defocus, a ...

Digital holography enables quantitative phase imaging based on interference. A digital hologram often encodes the phase information along with aberrations or deformations. This article reviews phase ...

Silica is a crafting material in Ark: Survival Ascended that can be used in several recipes. It is most commonly used to make Saddles and clothing items. Silica Pearls are only found underwater and ...

Considering patients' spherical aberrations may allow a better contact lens-wearing experience for patients with presbyopia. Wearing multifocal contact lenses alters spherical aberration and visual ...
