When did Ernst Ruska invented the electron microscope?
Ernst Ruska, a German electrical engineer, is credited with inventing the electron microscope. The earliest electron microscope was developed in 1931, and the first commercial, mass-produced instrument became available in 1939.
Why did Ernst Ruska make the electron microscope?
Max Knoll, Ruska developed an interest in the idea of electron microscopy. Realizing that optical microscopes were limited by the wavelength of the light beams used to view a specimen, Ruska determined that since electrons have much shorter wavelengths than light, they could be used to obtain greater resolving power.
What was the purpose behind the invention of electron microscopy?
The history of the electron microscope dates back to early twentieth century when the first electromagnetic lens was developed. This opened the door of possibility to use the principles of the lens to invent a microscope that could examine the structure of samples with greater detail.
