Near Infrared Spectrofluorometer


JASCO offers a Near Infrared (NIR) spectrofluorometer with the capability to measure materials with strong fluorescence in the NIR region, such as rare-earth elements or carbon nanotubes. Carbon nanotube characteristics change drastically according to the tube diameter or the chiral angle. A NIR spectrofluorometer is a very powerful tool for evaluation of these and other samples including 3-dimensional measurements that simultaneously scan both excitation and emission wavelengths.
