No. 1 in α Series: ADVANCES IN ELECTRON MICROSCOPY This is an objective lens pole piece for the Hitachi Perkin-Elmer HU-11A Elec- tron Microscope. It represents the cul- mination of one half million scientist and engineer hours of research and development. It is one element in the remarkable imaging system of the HU- 11 A. The electron optics of this instru- ment are unmatched in performance and versatility. Introduced one year ago, the enormous potential of the HU-11A as a fundamental research tool is now being realized in nearly 100 laboratories throughout the world. Its guaranteed resolution is 7A. The background electron micrograph on this page shows the (111) orienta- tion of single crystal gold. The spacing of the vertical lines is 2.35A. It was taken by the tilted illumination method. The total magnification is 6,700,000. This extraordinary micrograph was ob- tained with a standard Model HU-11A by an expert electron microscopist un- der controlled conditions at the Hitachi Central Research Laboratory in Koku- bunji, Japan. It is by far the highest resolving power demonstrated to this time by any electron microscope. Perkin-Elmer, as exclusive U.S. distribu- tor, is proud to be associated with this milestone achievement in Electron Microscopy. A print of this electron micrograph and complete information on the HU- 11A can bo obtained by writing to: The Perkin-Elmer Corporation, Distrib- utor Products Department, 751 Main Avenue, Norwalk, Connecticut.

ADVANCES IN ELECTRON MICROSCOPY This is an objective lens pole piece for the Hitachi Perkin-Elmer HU-11A Electron Microscope. It represents the culmination of one half million scientist and engineer hours of research and development. It is one element in the remarkable imaging system of the HU-11 A. The electron optics of this instrument are unmatched in performance and versatility. Introduced one year ago, the enormous potential of the HU-11A as a fundamental research tool is now being realized in nearly
100 laboratories throughout the world. Its guaranteed resolution is 7A. The background electron micrograph on this page shows the (111) orientation of single crystal gold. The spacing of the vertical lines is 2.35A. It was taken by the tilted illumination method. The total magnification is 6,700,000. This extraordinary micrograph was obtained with a standard Model HU-11A by an expert electron microscopist under controlled conditions at the Hitachi Central Research Laboratory in Koku-
bunji, Japan. It is by far the highest resolving power demonstrated to this time by any electron microscope. Perkin-Elmer, as exclusive U.S. distributor, is proud to be associated with this milestone achievement in Electron Microscopy. A print of this electron micrograph and complete information on the HU-11A can bo obtained by writing to: The Perkin-Elmer Corporation, Distributor Products Department, 751 Main Avenue, Norwalk, Connecticut.
