A primary benefit of using transmission electron microscopes (TEM) is their ability to reveal internal structures of specimens and provide a detailed 2D view. TEM works by transmitting a beam of electrons through a very thin sample, allowing the visualization of fine details within the cell or tissue. This capability is crucial for studying cellular organelles, complex structures, and even molecular arrangements, which other types of microscopy may not adequately resolve.

The resolution offered by a TEM is much higher than that of light microscopes, enabling scientists to see structures at the nanometer scale. Consequently, this technique is heavily utilized in fields such as cell biology and materials science to enhance our understanding of intricate biological systems and material properties. The generation of a 2D view facilitates the examination of these internal details, providing valuable insights into the architecture and function of cells and tissues.
