The phase contrast between the two rays can be detected with the human eye using particular optical filters.

Image quality, when used under suitable conditions, is outstanding in resolution and almost entirely free of artifacts unlike phase contrast.

A compound microscope also makes more advanced illumination setups, such as phase contrast possible.

The use of phase contrast does not require staining to view the slide.

They include brightfield Becke line, oblique, darkfield, phase contrast, and objective stop dispersion staining.

This collecting nucleolus was easily visible in phase contrast even without pretreatment due to its large size and particular structure.

The above describes negative phase contrast.

This led Knöll to cooperate with the Zeiss factory in the development of phase contrast and fluorescent microscopy.

Typical cases where this condition can be obtained are bright field, phase contrast, polarized microscopes.

Containing foamy and pale yellow contents, they are a refractive yellow color under phase contrast.
