WebNA is widely used to specify microscope objectives. NA allows for a precise calculation of the point spread function (PSF) and the modulation transfer function (MTF) The … WebOptical resolution describes the ability of an imaging system to resolve detail, in the object that is being imaged. An imaging system may have many individual components, including one or more lenses, and/or recording and display components. Each of these contributes (given suitable design, and adequate alignment) to the optical resolution of ...
