WebFeb 26, 2007 · MTF is the spatial frequency response of an imaging system or a component; it is the contrast at a given spatial frequency relative to low frequencies. Spatial frequency is typically measured in cycles or line pairs per millimeter (lp/mm), which is analogous to cycles per second (Hertz) in audio systems. Lp/mm is most appropriate for film cameras, … WebFigure 1 shows an architecture such as this in schematic form. However, when measuring the MTF of high-NA microscope objectives, for example with an NA >0.70, we begin to run into two significant obstacles. First, the NA of the relay lens (consisting of the microscope objective and tube lens in Figure 1) must exceed that of the lens under test ...
