摘要:
A brief historical review of the development of the electron supermicroscope is given. This is followed by a theoretical discussion of the resolving power attainable with the instrument and a summary of the important results which have been obtained by other workers. A description is given of the supermicroscope which has been recently constructed in Toronto. A number of photographs taken with the instrument demonstrate its high resolving power and its applicability as a tool in the sciences.

摘要:
The effect on the intensity distribution of point to point variation of the chromatic error in electron microscope images is investigated qualitatively. The intensity distribution in the image is found to possess a maximum value just outside, and a minimum value just inside, the image of the edge of the object. The deductions are verified by microphotometer traces taken across the photographic record of the image of a diatom edge. It is suggested that the intensity distribution curve may be used in the physical analysis of the object.
