Consequently, the overall system size increases substantially to accommodate a huge projection lens when the DMD size grows with its resolution. Another issue is associated with the common problems of low efficiency and poor uniformity in project ...

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
