It is especially to be noticed that the resolving power does not depend directly upon the closeness of the ruling.
The resolving power of the interferometer is found to be somewhat more than double that of a telescope of the same aperture.
Merely to show the dependence of resolving power on aperture it is not necessary to use a telescope at all.
The actual finiteness of λ imposes a limit upon the separating or resolving power of an optical instrument.
The reason of the augmentation of resolving power with aperture will now be evident.
The resolving power of a telescope with circular or rectangular aperture is easily investigated experimentally.
There is clearly no theoretical limit to the resolving power of gratings, even in spectra of given order.
The visibility of a star is a question of brightness simply, and has nothing to do with resolving power.
The resolving power and the width of the emergent beam fix the optical character of the instrument.
resolving power n.
The ability of a lens to distinguish small objects in close proximity.
