WebStep 4: Building a Light Supply. A key difference in a fluorescence microscope is the light supply. Instead of white light (i.e. many wavelengths) that is used in brightfield microscopes, fluorescence microscopes require light of a specific color (i.e. a narrow range of wavelengths). For example, blue light has a wavelength around 488nm.
