WebAccording to the Rayleigh criterion, it is just possible to distinguish the image formed by two points when the center of one Airy disk overlaps with the first-order dark ring of another Airy disk. At this time, the distance between the center of the two Airy patterns is equal to the radius of the Airy disk. WebAgain, if we assume a wavelength of 514 nm to observe a specimen with an objective of NA value of 1.45, then the axial resolution will be 488 nm. The Rayleigh Criterion is a slightly refined formula based on Abbe’s diffraction limits: R= 1.22 λ/NA obj + NA cond. Where λ is the wavelength of light used to image a specimen.
