Sentences with phrase «phase contrast»
"Phase contrast" refers to a way of enhancing the visibility of transparent objects under a microscope. It helps make these objects, which are more difficult to see, stand out by highlighting the differences in their density and thickness compared to their surroundings. Full definition
