WebIn the dark-field images, the edges of the cell produced intense scattering that strongly interferes with the observation of organelles inside the cell. In addition, the cell features appear to be larger due to the use of a small N.A. objective. DIC microscopy gives the best image quality in terms of contrast, lateral, and axial resolutions. Dark-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. In optical microscopes a darkfield condenser lens must be used, which directs a cone of light aw… camping stove wood burner
