发明名称 ELECTRON MICROSCOPE DEVICE
摘要 The present invention provides an electron microscope device, comprising a scanning electron microscope 2 and an optical microscope 3, wherein the scanning electron microscope has scanning means 10 for scanning an electron beam and an electron detector 12 for detecting electron 11 issued from a specimen 8 scanned over by the electron beam, and the scanning electron microscope acquires a scanning electron image based on a detection result from the electron detector, the optical microscope has a light emitting source 13 for illuminating an illumination light, and the optical microscope illuminates the illumination light to the specimen, and acquires an optical image by receiving a reflection light from the specimen, and wherein the electron detector has a fluorescent substance layer for electron-light conversion, a wavelength filter for restricting so that all or almost all of wavelength ranges of the fluorescent light from the fluorescent substance layer passes through, and a wavelength detecting element for receiving the fluorescent light passing through the wavelength filter and performing optical-electric conversion, wherein the light amount of the illumination light in the wavelength range passing through the wavelength filter does not exceed a limit of deterioration of the scanning electron image.
