Sample illumination is transmitted white light and contrast in the sample is caused by absorbance of some of the transmitted light in dense areas of the sample.
2) Dark field microscopy
Dark field microscopy describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen is generally dark.

specimens such as grains, gbs, cracks, ppts can be distinguished because they differ in contrast, caused by the differences in (a) the amount of light absorbed and (b) the inclination of those atomic planes that reflect the light
