WebAt the 1/e^2 points, the intensity I is 13.5%. This diameter contains 86.5% of the power in the beam, not so very different to the 83.8% in the Airy disk stated earlier for uniform illumination over the entire aperture. The FWHM points occur where the intensity I = 0.5, i.e., where x/wo = 0.59. WebUsing dimensionless coordinates, the radius of an Airy Disk is 3.83 Optical Units. About 84% of the total light intensity is in the central disk, the remainder 16 % is distributed in the concentric rings. An Airy disk is the projected image of a single point object in a microscope, so you can see it as the 'brick' component of the recorded image.
