  • Patent number: 10964510
    Abstract: A scanning electron microscope includes a first detector for detecting electrons, a second detector for detecting X-rays, and an image processor section for causing first markers indicative of imaging positions and second markers indicative of analysis positions to be displayed on a display device such that the first and second markers are placed on a whole image of a sample. The image processor section alters the magnification of the whole image based on instructions for altering the magnification of the whole image displayed on the display device. The image processor section displays new first markers of the same size as the first markers placed on the unaltered magnification whole image such that the new first markers are placed on the altered magnification whole image. The image processor section causes new second markers of the same size as the second markers placed on the unaltered magnification whole image to be placed on the altered magnification whole image.
