WebThe measurement process with the ImageMaster® Afocal is manual or fully automated. The measurement is possible for finite and infinite object distances. A wide range of parameters such as the MTF or magnification are already measured in the standard configuration. Specific measurements such as parallax (free distance) can be easily performed ... WebIn short, MTF is a measurement of the optical performance of a lens. More specifically, MTF shows the ability of a lens to resolve detail and transmit contrast (light colors remain light … 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). These curves offer a composite view of how optical aberrations affect performance at a set of fundamental parameters set by application need. shutdown domain controller for maintenance
