WebA Phase Contrast Microscope depends upon a specimen having structures that have different densities so that their volumes have different refractive indices. The phase contrast microscope has a condenser on its illumination that creates a ring of light that strikes the specimen at an angle. 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 …
