Bright field microscope function
WebMicroscope Anatomy & Function. Illuminator. There is an illuminator built into the base of most microscopes. The purpose of the illuminator is to provide even, high intensity light at the place of the field aperture, so that light can travel through the condensor to the specimen. Back to Microscope. Web• Fluorescence microscopy is a unique way of using a microscope to discover facts about specimens that often are not shown by standard bright field microscopy. In bright field microscopy, specimens are illuminated from outside, below or above, and dark objects are seen against a light background. In fluorescence microscopy, specimens are self ...

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.
