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. WebBright field is a common method used to create an image and it is also the most basic one. It is similar to the classic methods which are used in light microscopy. In this mode the contrast formation is formed directly by diffraction and absorption of electrons in the sample.
