    摘要: A specimen cartridge fashioned of a good thermal conductor, with an outer frame being fashioned of heat insulating material, and with a connecting rod being fashioned of a poor thermal conductor. A temperature distribution of the specimen is uniform and a temperature drift is reduced, with a thermal expansion of a specimen cartridge tilting rod not affecting the tilting angle, thereby making it possible to perform various highly accurate observations and measurements with an electron microscope.

    摘要: The electron beam having penetrated a sample is projected on a field limiting plate having an opening by means of an objective lens. That part of the electron beam which has passed through the opening of the field limiting plate, is projected upon a viewing screen by means of an image forming lens system. An electron beam deflection system is disposed between the hind focal point of the objective lens and the field limiting plate, the system having its deflection center at the hind focal point of the objective lens.

    摘要: A scanning transmission electron microscope (STEM) has an electron source for generating a primary electron beam and an electron illuminating lens system for converging the primary electron beam from the electron source onto a specimen for illumination. An electron deflecting system is provided for scanning the specimen with the primary electron beam. The STEM also has a scattered electron detector for detecting scattered electrons transmitted through the specimen. A projection lens system projects the scattered electrons onto a detection surface of the scattered electron detector. An image displaying device displays the scanning transmission electron microscope image of the specimen using a detection signal from the scattered electron detector. A detection angle changing device for establishes the range of the scattering angle of the scattered electrons detected by the scattered electron detector. This structure enhances the contrast of a desired portion of the specimen under observation for a scanning transmitted image by selective establishment of detection angle ranges for the scattered electron detector.
