Dispersion

In statistics, the placement of data points along a chart relative to an average or mean line. Dispersion is important to finance as the data points of say, a stock, determine the mean, which in turn helps determines the stock's trend. Dispersion is also used to determine volatility: data points all over the chart indicate that a stock has wild fluctuation in price.

Greenacre was well aware of the effects of colour fringes that could be produced from spectral dispersion or chromatic aberration and both Greenacre's paper and the 1964 USAF report stipulated that other bright areas were repeatedly checked for similar colour and none were found.
There is the problem of lateral chromatic aberration due to the wedge at the outer rim of the objective lens, but this has been reduced to a minimum by having a very long focal length.
Which of the following regarding ocular chromatic aberration is FALSE?
This new lens has been engineered for outstanding optical performance and durability and includes two new fluorite lens elements for improved quality and reduced chromatic aberration.
The new lens has been engineered for the ultimate in optical performance through the use of two fluorite lens elements for improved quality and reduced chromatic aberration.
Additionally, the same IC can concurrently correct for color and brightness uniformity variations on displays and correct for distortions and aberrations of lenses, including pincushion and barrel distortions as well as for chromatic aberration and lateral color separation.
6 IS STM telephoto zoom lens features one UD lens element, reducing chromatic aberration throughout the zoom range for excellent image quality with high resolution and contrast.
The optical construction consists of 13 optical elements in nine groups including three Extra-low Dispersion (ED) glass elements and one Super ED glass element that effectively minimize chromatic aberration, even at the widest aperture settings.
Both lenses also achieve a higher level of image quality through the incorporation of two fluorite optical lens elements which help to minimize chromatic aberration and eliminate color blurring around the edges of the subject.
Extra-low dispersion (ED) glass for chromatic aberration compensation and clearer viewing
