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. WebThe Rayleigh criterion for the diffraction limit to resolution states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other. See Figure 2 (b). The first minimum is at an angle of θ = 1.22λ/D θ = 1.22 λ / D, so that two point objects ...

WebCriterio de Rayleigh. El criterio de Rayleigh es una propuesta de John Rayleigh ( 1842 - 1919 ), que expone que dos líneas espectrales son todavía distinguibles si el máximo de uno coincide con el primer mínimo del otro. La característica esencial de este criterio es que las franjas son precisamente resolubles cuando la irradiancia ... WebIB Physics SL revision - OPTION A (Wave Phenomena) 4 - Rayleigh criteria2. Here is a 3D graphic of two images that are resolved and unresolveddue to diffraction. The onset of diffraction is gradual; prior to limiting resolution, it can still reduce small-scale contrast by causing airy disks to partially overlap.
