The false colouring of the image is due to chromatic aberration. The pencil of light proceeding from a point, converges, not to one point, but to a short line of varying colour. chromatic aberration | American Dictionarychromatic aberration noun[ U ] us/kroʊˈmæt̬·ɪk ˌæb·əˈreɪ·ʃən/ physics a failure of colors to be seen correctly through a lens (= curved piece of glass), caused by the lens not being perfect Examples of chromatic aberrationchromatic aberration Homogeneity is constrained by optical parameters such as chromaticaberration, whereas stability is controlled by the power supply and operating temperatures. Einthoven first explained chromaticaberration in the eye, which means that the eyes will not focus all the colors at the same time.

Gregory pointed out that a reflecting telescope with a parabolic mirror would correct spherical aberration as well as the chromaticaberration seen in refracting telescopes.

Ardenne applied the scanning principle not only to achieve magnification but also to purposefully eliminate the chromaticaberration otherwise inherent in the electron microscope.

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.
