Spectrofluorometer StellarNet

These instruments are miniature fiber optic spectrometers used to measure fluorescence. They connect to a sampling area using a 1000um fiber optic cable. The units have a spectral range of 350-1000nm or 200-850nm or 250-900nm depending on the model selected. The detector is a highly sensitive Charge Coupled Device (CCD) which provides 7 decades of dynamic range. The spectrograph has a permanently installed slit to set the spectrofluorometer optical resolution to at 6nm.

Operationally, the spectrofluorometer is connected to a fiber optic cuvette sample holder or directly to a fiber optic chemical sensor. In either case, the sample is excited with a specific range of light wavelenths and then monitored for fluorescent emissions at higher wavelengths. Additional optical channels can be attached to configure for traditional dual-beam and other multi-beam process monitor configurations.
