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. how do witches look like

WebLight from different parts of the circular aperture interferes constructively and destructively. The effect is most noticeable when the aperture is small, but the effect is there for large apertures, too. Figure 1. (a) Monochromatic light passed through a small circular aperture produces this diffraction pattern. WebThis figure plots the ratio of the numerical apertures of the condenser and objective versus the minimum resolved distance between Airy patterns (Rayleigh criterion) in units of wavelength divided by the objective aperture. When two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA ph of the seaWebCircular Aperture Diffraction. For monochromatic light of wavelength λ = nm. incident upon a circular aperture of diameter d = micrometers, d = x 10^ m, and projected on a screen at distance D = m, the displacement from the centerline on the screen is given by the relationship.
