An evaporated carbon replica technique for use with the electron microscope and its application to the study of photographic grains

Abstract

A method for the production of carbon replicas by evaporation on to the specimen is described. The specimen is subsequently removed by solution. The method has been applied to the examination of photographic grains, which could not be resolved in the optical microscope or observed directly in the electron microscope. A resolution better than 100 Å is obtained.
