The technique in microscopy of introducing a phase difference between parts of the light supplied by the condenser so as to enhance the outlines of the sample, or the boundaries between parts differing in optical density.

phase contrast microscopy
Example sentencesExamples
In addition, by 3-5 days after the temperature shift, early germ cells in many testes had abnormal morphology and appeared refractile in phase contrast, characteristic of dying cells.
Photomicrographs taken under fluorescence and phase contrast were scanned, and image analysis was performed using the shareware package Scion Image.
Birefringence is a description of the anisotropic dependence of the phase velocity of light in a sample on the incident polarization state; therefore, it provides polarization-based phase contrast.
Giant vesicles were observed either by phase contrast or by differential interference contrast with an inverted microscope (Axiovert 135, Carl Zeiss, Germany).
Images were obtained on a Zeiss Axiophot microscope equipped with fluorescence and phase contrast.
