Abstract
A method for producing a self-supporting electron-optical transparent structure that includes multi-layer strips and recesses located between the multi-layer strips. The method includes applying a first layer to a second layer, presetting a pattern by exposing or irradiating the first layer and etching the pattern out of the first layer so that partial areas of the second layer are uncovered. The method further includes galvanically applying layers to the uncovered partial areas of the second layer so that multi-layer strips are formed thereon and an electron-optical transparent structure is formed and removing the electron-optical transparent structure off the second layer.
