Describes the ability of a lens system, as a function of spatial frequency, to transfer object contrast to the image. Mathematically it is the ratio of the object to image contrast at each spatial frequency. At Optikos, our LensCheck™ LWIR, LensCheck™ VIS, OPTEST™ MTF Testing System, and I-SITE™ Electro-Optical Testing Systems all measure MTF among other things.
