a microscope that utilizes the phase differences of light rays transmitted by different portions of an object to create an image in which the details of the object are distinct despite their near-uniformity of refractive index.
Origin of phase microscope
First recorded in 1945–50
Also called phase-contrast microscope [feyz-kon-trast] /ˈfeɪzˈkɒn træst/.
