Correction of chromatic aberration by achromatisation involves the superimposition of the images produced at the different wavelengths.
For example, GRIN elements in a MWIR system can be useful for correcting chromatic aberrations, or color fringing, for night vision, navigation and medical imaging applications.
The highly-requested Automatic Lens Correction feature can dramatically improve the results possible with any lens by allowing users to apply profiles that correct for undesirable geometric distortions, chromatic aberrations and lens vignette effects that most lenses introduce to the image.
Offering exceptional optical performance to provide minimal distortion and chromatic aberrations while suppressing ghosting and flare, the advanced lens unit allows for higher shutter speed and captures stunningly clear images.
The use of the fluorite element and five UD elements helps to minimize secondary chromatic aberrations and produce better image quality with improved contrast and resolution through the entire zoom range; the end result is an optically precise lens worthy of becoming the leader of Canon's L-series lenses.
The design includes two ED (extra low-dispersion) elements and one double-sided aspherical element, plus four elements with a convex surface facing the subject, which combine to reduce spherical and chromatic aberrations.
An innovative in-camera Lens Correction function that electronically adjusts for Distortion and Lateral Chromatic Aberrations to maximize image quality with DA series lenses.
As it is an apochromatic lens, chromatic aberrations are corrected by lens elements made of special types of glass with exceptional partial dispersion.
ED elements reduce secondary chromatic aberrations and help the lens provide significantly sharper pictures throughout the 80-400mm zoom range.
The lifetime factory-aligned in-column OMEGA energy filter improves image contrast by completely eliminating chromatic aberrations.
The chromatic aberrations are therefore significantly below the defined limits.
