Applying aspheric treatments to cataract and refractive surgery procedures can significantly reduce spherical aberration and the consequent effects of glare and haloes, improving postoperative ...

After surgery, spherical aberration in photopic conditions ranged from –0.12 µm to +0.34 µm; spherical aberration in mesopic conditions ranged from –0.14 µm to +0.55 µm.

Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely eliminate spherical aberration in optical lenses ...

To demonstrate the results of the ray tracing-type aberrometer in measuring spherical aberration (SA) in pseudophakic eyes with monofocal intraocular lens (IOL), aspheric monofocal IOL ...

AN account of the recognised methods of investigating the spherical aberration of the eye is given by Tscherning, “Rapports presentés au Congrès international de Physique réuni à Paris en ...

Let’s look at this fun, and quite intriguing new lens and explore how this controllable spherical aberration feature can help shooters find interesting new compositions and shots to explore.

You can also invest in lenses like plano-convex and biconvex lenses, which minimize spherical aberration. Aberration can either be axial (longitudinal) or lateral (transverse). Axial aberration ...

As light travels through the optical system, many of thesesystems will experience some level of spherical aberration. This results inloss of image quality and can lead to a compromise in overall ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

The Portrait Heliar 75mm F1.8 is the company's first lens with controllable spherical aberration, allowing photographers to adjust the look of the bokeh. Cosina designed its Portrait Heliar 75mm ...
