Bright field bf
WebBright field microscopy is the conventional technique. It is suitable for observing the natural colors of a specimen or the observation of stained samples. The specimen appears darker on a bright background. In order to increase the contrast, one should close the condenser. This will reduce the resolution, but there is a positive trade-off. WebNov 5, 2024 · In the bright field (BF) mode of the TEM, an aperture is placed in the back focal plane of the objective lens which allows only the direct beam to pass. In this case, the image results from a weakening of …
