Rayleigh criterion depth of focus
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 ... WebFeb 1, 2004 · Abstract. The use of lithography to redevelop Lord Rayleigh's criteria for resolution and depth of focus was discussed. The distance between wavefronts is called …

WebNumerical Aperture (NA) = η • sin (α) (1) where α equals one-half of the objective's opening angle and η is the refractive index of the immersion medium used between the objective and the cover slip protecting the specimen (η = 1 for air; η = 1.51 for oil or glass). By examining Equation (1), it is apparent that the refractive index is ... Webmembers.
