WebThe theoretical maximum optical resolution of optics is determined by diffraction effects of light which mainly depend on the wavelength of the light and the slit (aperture). According to the Rayleigh criterion (remaining contrast of approx. 15 per cent), two image points can still be distinguished when the distance of the points dx = 2 * 1.22 * f-stop * wavelength. WebThe Rayleigh criterion stated in the equation θ = 1.22 λ/D gives the smallest possible angle θ between point sources, or the best obtainable resolution. Once this angle is found, the …
