Max and practical Ernst Ruska built the first electron microscope in 1931. Transmission electron microscopes facilitate Morphological information at the scale of an atomic diameter. And also facilitates the observation of crystallographic and other Biochemical details within a few Square Nanometer areas
In which, the specimen must prepared in skinny Section because a beam of the electron transmitted through the sample to produce images on a phosphor screen.
In the present thicker area of the specimen Where fewer electron avers transmitted and conversely, light regions of the image represent thin areas on the sample.
