The spectrofluorometer is a complex device, which features photomultiplier tubes, a photodiode, and in some cases, a charge coupled device detector. The devices can include a number of different components. The systems can come with a variety of different options as well. Some of the other components that many are using with their spectrofluorometer include polarizers, cryostats, filter holders, LEDs, slide holders, manual slits, computer controlled slits, near infrared detectors, and more. Some of the options are user friendly and are perfect for research study.
