CHECK THESE SAMPLES OF Bright Field Microscope
While the first method can be adopted with any bright field white light microscope assuming that light can be transmitted through the object under examination but in the second method, the stain emits light at a visible wavelength on illumination with ultraviolet light.... Microscopic methods involve examination of soil samples under a light microscope by using simple stains such as phenol aniline blue and fluorescent stains such as fluorescein isothiocyanate (FITC), acridine orange, rhodamine (fluoresces red), europium chelate (europium (iii) thenoyltrifluoroacetonate), DAPI (4'-6'-diamidino-2-phenyl-indole), ethidium bromide and Hoechst 33258 (bisbenzimide)....

The principle behind this optical illumination is to allow light to illuminate dense areas of samples, providing contrasting effect making them… In most cases, illumination technique by bright field light is made possible by applying stains to improve contrast by absorption by specimens.
Tissue sample removed from its immediate source should be fixated with fixing Fixation therefore preserves protoplasm, prevents autolytic changes and bacterial growth (Pawley, 2006, p....
