In scanning microscope the cathode ray tube of high resolution is used. The screen of this tube is formed by raster consisting of 4096×4096 luminous elements, composing the image. This raster allows to form images of investigated microobject on the screen in a wide range without loss of resolution. The accuracy of imaging on the screen depends on the current setting errors in inductive coils of deflection system. The ways of reducing the static error of the current set in a voltage-current converter are proposed.
