WebBright-field microscopy is a very basic, popular technique in which the magnified image appears dark against a white background. Thus, the name: a bright field. It is fairly easy to magnify with bright-field microscopy, but it is a more limited technique compared to others. In short, bright-field microscopy is most likely the technique your ... Bright-field microscopy (BF) is the simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light, and contrast in the sample is caused by attenuation of the transmitted light in dense areas of the sample. Bright-field … See more The light path of a bright-field microscope is extremely simple, no additional components are required beyond the normal light-microscope setup.
