Bright-field microscopy - Wikipedia
WebBright Field Microscopy With a conventional bright field microscope, light from an incandescent source is aimed toward a lens beneath the stage called the condenser, through the specimen, through an objective lens, and to the eye through a second magnifying lens, the ocular or eyepiece. Most microscopes will have a built-in illuminator. WebA bright-field microscope will work reasonably well to view the larger eukaryotic microbes (i.e. protozoa, algae) without stain, but unstained bacteria will be almost invisible. Stained bacteria will appear dark against a bright background (ah, I knew that there was a reason for the term “bright-field.”) Bright-Field Microscope good recent r rated films
