Abstract
This paper describes a numerical development of image converters and intensifiers which incorporate an inverting electron optical system EOS and a microchannel plate MCP as an amplifier The numerical design of the system includes calculation of the electrostatic field in the device trajectories of electrons emitted from a photocathode and determination of the modulationtransferfunction MTF which gives the objective estimation for the image qualityResults of the numerical experiments are shown and the EOS with optimized characteristics is developed It provides the nearly flat image surface determines the position of the surface of the best focus minimizes the image distortion and reduces a noise factor of the MCP
