ABSTRACT:
A specimen image display apparatus is disclosed in which a specimen signal generated when the surface of a specimen is radiated while being scanned by an electron beam is detected, and this detection signal is used to display a magnified image of the specimen on a cathode ray tube. In addition to the specimen image, a scale of fixed length which remains unchanged regardless of the magnification of the specimen image and a character indicating converted scale are displayed on the cathode-ray tube, thus improving the accuracy of the measurement of the length of the specimen image on the cathode-ray tube.
