Chromatic aberration does not occur in a mirror because chromatic aberration is caused by the different colors of a light being bent different amounts. Mirrors do not care about the different colors as they only relfect the light instead of refracting it.

Why does a reflecting telescope have no chromatic aberration?

There's no aberration with the main MIRROR of the telescope, because light doesn't go through the mirror. A reflecting telescope will have SOME chromatic aberration, because every reflecting telescope has at least one refracting lens; the eyepiece. Light goes THROUGH that lens, and light passing through the glass lens will generate some chromatic aberration.


What causes chromatic aberration in the objective lens of a telescope?

The most chromatic aberration would occur with a single-lens refractor. However, today most telescopes employ at least two lenses, called achromats. These still incur significant chromatic aberration if the telescope has a short focal length to aperture ratio, called focal ratio. An easy way to determine if the telescope will have significant chromatic aberration is to divide the focal ratio of the telescope by the diameter of the lens in inches. A value of 5 or higher indicates minimal chromatic aberration; 3 to 5 is moderate aberration, and 3 and under is significant chromatic aberration. However, chromatic aberration is generally only obvious on bright stars or planets.


Which design subject to chromatic aberration?

prime focus reflector


Early telescope makers compensated for chromatic aberration by?

Newton realized that mirrors do not cause chromatic aberrations, and built a telescope using them.


Why is chromatic aberration a prime consideration in designing a telescope objective?

Chromatic aberration refers to the inability of a lense to focus all the wavelengths of light to the same point. Because of this, the images in a telescope will be less acurate and less focused. A large telescope with a huge aperture but very bad chromatic aberration would not be of much use to a scientist or even an amatuer astronomer because of these limitations.


Why do thick lenss show chromatic aberration but thin lenss do not?

because thick lenses have small focal length . this causes chromatic aberration. hence it can be minimised by increacing the focal length of lens or by using thin lenses which have high focal length.


What is the color distortion caused by lenses called?

color disortion from lenses is called chromatic aberration

What is it called when color appears to change with light?

It might be called photo-chromatic aberration.


Why is chromatic aberration more evident for some positions of the aperture?

The further the aperture is from the optical axis of the lens, the more to the side of the lens the incident light falls. The further the light falls from the optical axis, the greater the effects of chromatic aberration. This is because different wavelengths of light have different refractive indices (dispersion). Because of Snell's Law, n1sintheta1=n2sintheta2, the greater the angle of incidence, the more pronounced the effects of the difference in refractive indices. Spherical aberration further enhances the chromatic dispersion.


A telescope that suffers from chromatic aberration and has a low light gathering power is most likely?

a. a small diameter reflecting telescope.
