Light collected (by lens L1) from a light source passes through a monochromator, which isolates a single wavelength (actually, a narrow band of wavelengths) from the source. This light is focused (by lens L2) into the sample solution, which absorbs the light and emits fluorescence photons in all directions. basilar infiltrate lung
