    Numerical aperture of a Keplerian telescope

    Homework Statement [/B] Design an afocal Keplerian telescope to imagine an object of ##L = 5\, mm## with a resolution of ##R = 2\, \mu m## and a magnification of ##M=-2##; assume that the wavelength is ##\lambda = 500\, nm##. Don't use lenses faster than ##F/1##. Using the optical invariant...
