Web(2)(f/#)w ≈(1+m)×(f/#) ( f / #) w ≈ ( 1 + m) × ( f / #) In the equation for (f/#) w, m represents the magnification (ratio of image to object height) of the lens. Note that as m approaches zero (as the object approaches infinity), (f/#) w approaches f/#. It is especially important to keep (f/#) w in mind at smaller WDs. WebBoth equations are in fact structurally similar with Abbe limit given by d = λ 2 N A. And Rayleigh limit given by d = 1.22 λ 2 N A = 0.61 λ N A. where lambda is the wavelength and N A the numerical aperture of the light collecting lens.

WebDiffraction is not only a problem for optical instruments but also for the electromagnetic radiation itself. Any beam of light having a finite diameter D and a wavelength λ exhibits diffraction spreading. The beam spreads … The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a principal limit to the resolution of any optical system, due to the physics of diffraction. An optical system with resolution performance at the instrument's theoretical limit is said to be diffraction-limited.

This includes the imaging lens, camera sensor, image capture boards, and video cables, for instance. The resulting MTF of the system is the product of all the MTF curves of its components (Figure 7).
