Abstract
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.
