WebThis calculator is based on the Rayleigh criterion, which states that the Airy disks should be at least one radius apart. The radius of an Airy disk is the distance from the center to the first zero. Mathematically, the minimum angle that can be resolved based on this criterion is. \alpha = \dfrac {1.22 \lambda} {D} α = D1.22λ. http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/slits.html
