In microscopy, the term "phase" typically refers to phase contrast microscopy, a technique that enhances the contrast of transparent or low-contrast biological specimens by exploiting differences in refractive index within the specimen. Phase contrast microscopy allows for visualization of cell structures and organelles that would otherwise be difficult to see with traditional brightfield microscopy.
Contrast in microscopy refers to the ability of the specimen to be distinguished from its background. Techniques such as staining, phase contrast, and differential interference contrast (DIC) microscopy can enhance contrast in microscopy.
Phase-contrast microscopy is the observation of internal structures of living microbes where as bright field microscopy is the observation of killed stained specimens and naturally colored live ones.
Vaporization
Phase contrast microscopy is often used for viewing colorless specimens, as it enhances the contrast between different parts of the specimen based on density differences. This type of microscopy is particularly useful for observing live biological samples without the need for staining.
Some disadvantages of phase contrast microscopy include lower resolution compared to other techniques such as fluorescence microscopy, difficulties in distinguishing different refractive index structures that are similar, and the requirement for careful alignment and calibration for optimal results.

Vaporization
Phase contrast microscopy enhances the visibility of transparent samples by converting differences in the phase of light passing through the sample into differences in brightness, making subtle variations in the sample more visible. This technique uses special optical components to create contrast in transparent samples that would otherwise be difficult to see with traditional brightfield microscopy.

transmission electron microscopy
Phase contrast microscopy is commonly used to view colorless specimens by enhancing the contrast between the specimen and its background. This technique allows for visualization of transparent or unstained samples without the need for specialized staining protocols.
Hanging drop can be observed for longer periods of time without drying out.
