Fluorescence microscope light path

WebThe illustration below shows the typical light path of an epifluorescence microscope. Most microscopes that are used for cell biology are arranged so that the light travels through the objective lens to illuminate the sample, and then the light emitted from the sample travels back through the same objective to the detector. http://labs.bio.unc.edu/Bloom/Bio188spring05/Julie%20and%20TEd%20microscope%20alignment%20protocol.pdf
