WebWith a dark field microscope a special aperture is used to focus incident light meaning the background stays dark. The light does not pass directly through the sample being studied. Instead light is reflected off the specimen, making it appear to be emitting light. curner hobby lobbyDark-field microscopy (also called dark-ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e., where there is no specimen to scatter the beam) is generally dark.
