WebThe first basic principle of through-focus MTF is the geometrical limitation. Any lens that focuses light produces an “illumination cone.”. See below for an example: The light from the lens comes to a focus and then expands again, as it should. The diameter of the illumination cone (called the spot size) is very small at the focus but it is ... WebThe modulation transfer function (MTF) curve is an information-dense metric that reflects how a lens reproduces contrast as a function of spatial frequency (resolution).

"WebThe modulation transfer function (MTF) is calculated by Fourier transforming the PSF (of green light only) and taking the absolute value. The MTF is plotted below. We see that the MTF is eventually limited by the 4 micron spacing between the green pixels, meaning that the maximum resolution is 125 cycles per mm (0.5/4 micron). " - Optics mtf
