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 ...

This was clearly stated by Rayleigh himself in 1879: 2 This rule is convenient on account of its simplicity; and it is sufficiently accurate in view of the necessary uncertainty as to what exactly is meant by resolution. soft teeth in children

"Webow; this is Rayleigh’s criterion, i.e. that the ow must have an in ection point. Another way to think of this is in terms of the vorticity of the background ow, = U y: (11) The statement of Rayleigh’s criterion is equivalent to the statement that y must change sign within the ow and therefore y= 0 (12) in some nite interval in the ow.
