F-number - Wikipedia, the free encyclopedia In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture[1]) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil.[2] It is a dimensionless number that is a quantitative mea

Diffraction - KenRockwell.com: Photography, Cameras and Taking Better Pictur Diffraction is a loss of sharpness or resolution caused by photographing with small f/stops. The same softening effect happens when photographing through diffusion cloth or window screens. Anytime you look or photograph through small holes ...
Diffraction-limited system - Wikipedia, the free encyclopedia 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 fundamental maximum to the resolution of any optical system which is due
