Difference Between Brightfield and Darkfield Microscope

WebHow to spot the difference between "dark" and "bright" patterns using behavioural design? Our guest Joey Thompson (Growth Designer at Miro, ex. Intercom)… In optical microscopy, dark-field describes an illumination technique used to enhance the contrast in unstained samples. It works by illuminating the sample with light that will not be collected by the objective lens and thus will not form part of the image. This produces the classic appearance of a dark, almost black, background with bright objects on it. The steps are illustrated in the figure where an inverted microscope is used.
