Light is focused on the specimen and it absorbs the light and the contrast image that is dark is viewed against a bright … We have compared the application and results of bright and dark field lighting geometries, but there are some usage criteria to consider for each Directional or partial BF lights are the most versatile from a positioning standpoint, so long as they don’t produce specular glare. For example, try imaging the surface … See more Bright field can be divided into two sub-techniques, differentiated primarily by solid angle, which is generically defined as a measure of the amount of relative area from which the light … See more Figures 3a and 3b illustrate the results of how BF and DF light responds differently on a flat, mirrored surface. To fully understand how dark field light is produced and used, it is important to remember a simple … See more While either image is likely suitable as-is, consider if the next part had significant dark staining. The DF image likely would not change, whereas the BF image may make the stain … See more

WebFlat-field correction (FFC) is a technique used to improve quality in digital imaging. It cancels the effects of image artifacts caused by variations in the pixel-to-pixel sensitivity of the detector and by distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.
