Explore our microscopes for education, training, laboratories, and leading-edge research in the life science fields, such as pathology and cytology. Transmission electron microscopes (TEMs) use a beam of electrons to examine the structures of molecules and materials at the atomic scale. As the beam passes through a very thin sample, it interacts with the molecules, which projects an image of the sample onto the detector (often a charge-couple device; CCD). of the microscope and the image of the specimen will appear light against a dark background. This scattering of light leads to an enlargement of the specimen, thus the dark field microscope is particularly useful for the examination of material that is beyond the resolution of a bright field microscope. The specimen used for dark field microscopy
