Microscope seen as a telescope. (a) A microscope’s resolution is determined by the numerical aperture NA of its objective, which is defined as the product of the index of refraction of the medium between the objective and the sample, n, and the sine of the half angular aperture, θ. (b) A telescope’s angular resolution is determined by its (physical) aperture, D. The intensity profile and diffraction spots were plotted using a simple Python script.
