WebBy Alec De Grand - 17 December, 2024. Darkfield microscopy is a technique that takes advantage of oblique illumination to enhance contrast in specimens that are not imaged well under normal illumination conditions. After the direct light has been blocked by an opaque stop in the condenser, light passing through the specimen from oblique angles ... WebApplications: In cell biology, upright microscopes are used for phase contrast or widefield fluorescence microscopy of living cells or samples that are squeezed between a slide and coverslip. An additional application is the microscopy of fixed cells or tissue sections. In principle, upright microscopes can be used for live cell imaging ...
