The Korea Research Institute of Standards and Science has developed a detachable acoustic lens that allows for easy ...

Reducing the shutter speed can yield some nice effects similar to using the SA (Spherical Aberration) control on a Canon RF 100mm f2.8 macro lens (yes, I have one), which yields a dreamy soft-focus ...

The problem? The highly anticipated images were blurry. Hubble had a flaw in its mirror called a "spherical aberration." It would require a new mission, a repair job in space by astronauts ...

Fujifilm says the all-important fixed lens can suppress spherical aberration and field curvature thanks to a 10-element, eight-group configuration that includes two aspherical lenses. It uses a ...

Rich Halley is a tenor saxophonist and composer based in Portland, Oregon. He is known for his fiery playing and imaginative compositions. Rich has released 26 critically acclaimed recordings as a ...

The achromatic doublet lens is used to minimize or eliminate chromatic aberration. Its achromatic design also helps to minimize spherical aberration. Compared with a single lens, an achromatic doublet ...

Wearing multifocal contact lenses alters spherical aberration and visual acuity outcomes in patients with early presbyopia, according to a crossover study published in Eye & Contact Lens. Considering ...

Trouble with one of the Hubble Space Telescope's three remaining gyroscopes, critical for aiming and locking onto targets, has prompted mission managers to switch to a backup control mode that ...

There are other issues to consider, as well. “A lens in the imaging chain may introduce noise, including chromatic aberration, spherical aberration, and errors associated with microscopic dust or lens ...

Patients who underwent refractive surgery for hyperopia may benefit from an IOL with neutral spherical aberration during a subsequent lensectomy. Implanting a trifocal intraocular lens (IOL) with ...
