Because of the … WebJan 19, 2024 · The Rayleigh Criterion is a slightly refined formula based on Abbe’s diffraction limits: R = 1.22λ/(NA obj + NA cond) where λ is the wavelength of light used to image a specimen. NA obj is the NA of the objective. NAcond is the NA of the condenser. The value ‘1.22’ is a constant. This is derived from Rayleigh’s work on Bessel Functions.
