develop Electrapane I t is o n e t h i n g for glass t o provide h i g h resistance t o electric current—but it9s another thing to make glass conduct! Libbey-Owens-Ford Research does it by c o a t i n g glass with a film—so that electric current can flow a l o n g the surface of the glass. T h i s c o n d u c t i n g glass is Libbey-Owens-Ford Electrapane. Specimens of experimental c o n d u c t i n g films are carefully studied by Libbey-Owens-Ford scientists with an RCA Electron Microscope—before and after application of electric current. T h e instrument clearly reveals the crystalline film structures heretofore in visible u n d e r light microscopes—because the RCA Electron Microscope can magnify* directly to 20,000 diameters and produce sharp photographic enlargements to 100,000 diameters! T h i s is o n e m o r e example of the way the R C A Electron M i c r o s c o p e is h e l p i n g industry develop p r o d u c t s for the future.

Plate Glass Samples—Coated for Electrical Conductivity (Ruled lines represent one micron of the original surface)
Film breakdown—after a heavy flow of electric current. Resistance goes up when this happens.
Plate glass specimen, coated with a thin film of electrical conducting material. The coating is invisible to the naked eye!
