- The history of the electron microscope dates back to the early twentieth century when the first electromagnetic lens was developed1. In 1933, a primitive electron microscope was built that imaged a specimen rather than the electron source, and in 1935 Knoll produced a scanned image of a solid surface2. The resolution of the optical microscope was soon surpassed2. A micrograph taken with a transmission electron microscope shows the atomic structure of a diamond surface2.Learn more:✕This summary was generated using AI based on multiple online sources.

Many developments laid the groundwork of the electron optics used in microscopes. One significant step was the work of Hertz in 1883 who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam. Others were focusing of the electrons by an axial magnetic field by Emil Wiechert in 1899, improved oxide-c…
