Fluorescent microscope light source
WebFluorescence Microscopy Light Sources In most fluorescence microscopy applications, the number of photons reaching the eye or other detector, such as a video camera, CCD digital camera system, or photomultiplier, is usually very low. WebAnother type of light microscopy is fluorescence microscopy, which is used to image samples that fluoresce (absorb one wavelength of light and emit another). Light of one wavelength is used to excite the fluorescent molecules, and the light of a different wavelength that they emit is collected and used to form a picture.
