Light waves that were farther away from the axis produced more
optical aberration, whereas those that were closer to the axis generated less
optical aberration.
Standard lens has inherent
optical aberration called field curvature.
In a short length, large objective, "fast" optical system, high-index glasses are utilized to minimize the radius requirements that assist in controlling
optical aberration. High-index glasses tend to separate the wavelengths more than low-index glasses do, making correction of this separation more challenging.
"This way, the digital slide created is perfectly focused everywhere and we are left with captured images that are free from
optical aberration, have no tiling artifacts, and are practically seamless.
Several basic chapters discuss wavefront analysis,
optical aberration changes after LASEK, the effect of alcohol on corneal cell-cell and cell-matrix interactions, and the pathogenesis and treatment options for postoperative stromal haze.
Using a deformable telescope mirror controlled by computer, researchers can compensate for the blurring by generating an
optical aberration exactly opposite that caused by the atmosphere.
NASA is planning to pay a service call on the Hubble Space Telescope to correct the
optical aberration that has stymied its ability to transmit high-quality scientific data.
However, as with any
optical aberration, field curvature can't be completely eliminated.
ANASA-appointed panel concluded last week that the space agency and the contractor it hired to build the Hubble Space Telescope's primary mirror deserve equal blame for not detecting -- prior to Hubble's launch -- the serious
optical aberration that today flaws the telescope's vision.

Optical aberration.
In a short length, large objective, "fast" optical system, high index glasses are utilized to minimize the radius requirements that assist in controlling
optical aberration. High index glasses tend to separate the wavelengths more than low index glasses do, making correction of this separation more challenging.
"Objective lenses are tailored to magnification with as little
optical aberration as possible.
optical aberration - an optical phenomenon resulting from the failure of a lens or mirror to produce a good image
