§êawki4fcwafé& The Philips Electron Microscope is a proved instru ment with numerous exclusive features which give it unmatched operating characteristics. Through the use of an intermediate lens system, mag nification is continuously variable from 1,000 to 60,000 diameters. Electron diffraction patterns can be derived from selected specific areas of the field by simple and instanta neous conversion from microscopy to electron diffraction techniques—without need for re-evacuation, change of pole shoes, specimen transferral or other inconveniences. Full descriptive data and detailed specifications are available without obligation. You are further invited to visit our application laboratories to see the Electron Micro scope in use on your problems—your samples.
