WebDarkfield microscopy can often create high-contrast, high-resolution images of specimens without the use of stains, which is particularly useful for viewing live specimens that might be killed or otherwise compromised by the stains. WebA dark field microscope is ideal for viewing objects that are unstained, transparent and absorb little or no light. These specimens often have similar refractive indices as their surroundings, making them hard to distinguish with other illumination techniques.
