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. WebMay 12, 2024 · Brightfield and epifluorescence micrographs were collected on the live cells using an orange TRITC filter set. Fluorinated SPcs all showed strong intracellular fluorescence relative to DMSO treated control cells, whereas the signal from SPc(B 3) was far weaker, albeit present. Two factors dictate the brightness of cell images: (1) the …

WebUsing bright field microscopy alone, these objects would nearly be invisible. The phase contrast optics of a microscope is able to convert the differences in the refractive index into a difference in brightness. Depending on the system used, the specimens will either appear bright on a dark background, or dark on a bright background.
