WebThe 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. NA obj is the NA of the objective. NA cond is the NA of the condenser. The figure of ‘1.22’ is a constant. This is derived from Rayleigh’s work on Bessel ...

"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. " - Rayleigh's criterion equation
