Instrument for viewing faraway objects

Nettet1. jan. 1989 · Telescopes Afocal systems are used to view faraway objects; hence the name telescope. For an object so distant that it can be considered to be at infinity, light from the various points of the object arrives in nearly parallel bundles, whose angular separation determines the object's perceived size. NettetIt claims that two images are just resolved when one image’s diffraction pattern is greater than the second image’s first minimum diffraction. The formula for the smallest angular distance between two just resolvable objects is given by Rayleigh’s criterion. The formula will be: θ=1.22λ/D. Here D = circular aperture.
