Abstract

Electron microscope imparted with measuring functions comprises an electron microscope system for forming an electron-microscopic image, a fluorescent screen for displaying the electron-microscopic image, and an optical microscope for observing the electron-microscopic image on the fluorescent screen. A pattern which provides convenience for measurements of the electron-microscopic image is imaged on an object plane of an eyepiece of the optical microscope.
