Fluorescence Lifetime Imaging (FLIM) produces an image based on the differences in the excited state decay rate from a fluorescent sample. The signal-to-noise ratio will be determined in part by the relative strength of the autofluorescence compared to the fluorescence of the exogenous probe. Fluorescence Microscopy ​ The CAF Fluorescence Microscopy Unit at Stellenbosch University in the Western Cape houses fluorescence -based instruments for . Fluorescence is a molecular phenomenon in which a substance radiates light energy almost instantaneously upon being struck with light from another source. Both fluorescence and phosphorescence are based on the ability of a substance to absorb light and emit light of a longer wavelength and therefore lower energy.

Fluorescence techniques were designed to observe and analyze the composition of samples, as well as interactions between various . The FLuorescence EXplorer (FLEX) mission will provide global maps of vegetation fluorescence that can reflect photosynthetic activity and plant health and . A fluorescence microscope is much the same as a conventional light microscope with added features to enhance its capabilities.
