摘要
A near-field photon transmission electron emission microscope, comprising: a. an image magnifying electron optical device comprising a cathode lens objective and an electron image detector, b. a vacuum housing having at least one port for a vacuum generating device, c. at least one electromagnetic radiation radiopaque an examination object and d. an examination slide characterized in that - the examination slide (4) between the examination subject (2) and the image magnifying electron optical arrangement is arranged, - the examination slide (4) channels (5) on the side of the examination subject (2) by in a common plane (3) lying floors (5a) are closed, on which the examination object (2) rests and which are open in the direction of the electron-optical arrangement and as a photon-electron converter (4) for the proportional conversion of the transmission image photons (1 ') the channels (5) form a matrix of openings (5b) on the opposite side of the examination object support (4) in the object plane of the cathode lens objective (8, 9, 9 ', 9 "), the channels (5) of the examination object carrier (4) are suitable by means of an emissive surface on the inner walls, p produce the roportional to the intensity of the photoelectron secondary electrons (13), - the electron-optical system with the cathode lens objective (8, 9, 9 ', 9 ") generates an enlarged electron image of the examination object (2) on an electron image detector (14).
