Web19 jan. 2024 · In microscopy, the term “resolution” is used to describe the ability of a microscope to distinguish details of a specimen or sample. In other words, the minimum distance between 2 distinct points of a specimen where they can still be seen by the observer or microscope camera as separate entities. Resolution is intrinsically linked to … WebTransmission Electron Microscopy. The transmission electron microscope (TEM) operates on many of the same optical principles as the light microscope. The TEM has the added advantage of greater resolution. This increased resolution allows us to study ultrastructure of organelles, viruses and macromolecules. Specially prepared materials …
