Examples of chromatic aberration


chromatic aberration
Homogeneity is constrained by optical parameters such as chromaticaberration, whereas stability is controlled by the power supply and operating temperatures.

Lenses for correcting chromaticaberration of the eye.
This result suggested that chromaticaberration might account, in part, for color assimilation over small, but not large, enclosed areas.
The ray tracing analysis yields a set of characteristics of interest to optical designers, including distortion, astigmatism, and chromaticaberration.
The major contributions were given by chromaticaberration and space-charge effect.
In this way, one may weaken the effects of both space charge and chromaticaberration.
The test grating was free of chromaticaberration, and contrast was compromised neither by the optics of the eye, nor by diffraction effects.
Evidence that the loss of the blue cone opsin is a positively selected trait lies in the fact that, without blue cones, the confounding effects of chromaticaberration are reduced.
The effect of chromaticaberration on visual acuity.
Chromaticaberration might account for the null difference between the two patterns for smaller widths, although this would not explain assimilative color perceived over wider contours.
This reduces the amount of chromaticaberration over a certain range of wavelengths, though it does not produce perfect correction.
