WebDec 17, 2024 · What Are the Advantages of Using Darkfield Microscopy? Darkfield microscopy has many advantages. Its dark background offers a high degree of contrast, making it easy to see samples on difficult backgrounds. This technique is easily accessible since many brightfield lab microscopes can be configured for darkfield illumination. WebDec 17, 2024 · Darkfield illumination is best for revealing outlines, edges, boundaries, and refractive index gradients. Ideal candidates for darkfield illumination include minute living aquatic organisms, diatoms, small insects, bone, fibers, hair, unstained bacteria, yeast, cells in tissue culture, and protozoa.

WebThe entire field appears dark when there is no sample on the microscope stage; thus the name dark-field microscopy. When a sample is on the stage, the light at the apex of the cone strikes it. The rays scattered by the sample and captured in the objective lens thus make the image.
