Brightfield vs darkfield microscope
WebAug 21, 2024 · Heavier atoms scatter electrons more intensely than lighter atoms. Hence, in bright field mode, the regions with heavier atoms are darker, while in dark field mode … WebLightfield Microscope Darkfield Microscope Special condenser deflects light rays so they reflect off the specimen at an angle. Only scattered light is collected. Darkfield microscope Light gathered by condenser and passed through specimen. Considering the simplicity of the setup, the quality of images obtained from this technique is impressive.

WebDarkfield microscopy is a simple and popular method for rendering unstained and transparent specimens clearly visible. Good candidates for darkfield observation often have refractive indices very close in value to that of their surroundings and are difficult to image with conventional brightfield techniques.
