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… WebSeveral techniques are commonly employed to introduce contrast in reflected light microscopy, including darkfield illumination, polarized light, and differential interference …

The contrast and resolution obtained with inexpensive dark field equipment may be superior to what you have with student … Bright-field microscopy typically has low contrast with most biological samples, as few absorb light to a great extent. Staining is often required to increase contrast, which prevents use on live cells in many situations. Bright-field illumination is useful for samples that have an intrinsic color, for example chloroplasts in plant cells. • Comparison of transillumination techniques used to generate contrast in a sample of tissue paper (1.559 …
