WebFeb 18, 2024 · Bright field lighting is the method for imaging reflected light. That is, the light coming from the source is reflected into the camera so that small defects and edges which typically scatter light are not picked up by the camera. This creates a bright image, but areas with engravings, scratches, or indentations may not be as well defined. WebAnnular bright-field (ABF): Same as BF, but instead of using a full disk for detection, only the outer annulus of the bright-field disk is used giving unique contrast effects; Annular dark-field (ADF): Collects the intensities of the scattered electrons (10 mrads < collection angle < 50 mrads)
