Lifetime fluorescence demand by industry — 2008.
Lifetime fluorescence is a subset of fluorescence spectroscopy in which the time between excitation and relaxation is measured, rather than just the intensity of the emitted energy. The technique is used primarily in biological applications, but has a number of other uses as well. Lifetime fluorescence is a well-established niche market.

Lifetime fluorescence typically measures the time it takes for molecules to fluoresce after being excited by a light source. Frequency domain lifetime fluorescence compares the modulation and phase-shift of the emitted energy relative to the excitation energy instead. An increasingly popular technique within the lifetime fluorescence market is FLIM, which stands for "Fluorescence Lifetime Imaging," and is very useful for examining biological tissues.

Lifetime fluorescence is by far most popular in biological analyses, which accounts for more than half of demand when considering academia, government, and hospital & clinical applications. There is limited application in areas such as electronics for developing LEDs, characterizing polymers in the plastics industry, and identification and characterization of crude oil in the environmental and oil & gas industries.

The total market for lifetime fluorescence was about $18 million in 2008. Despite the global recession, demand is not likely to contract drastically due to its connection to the healthcare, academic, and government areas. Longer-term annual growth is likely to be in the low single digits.
