OmniFluo are modular fluorescence systems. By different accessories, Omnifluo could realize application changes and specifics measurements: fluorescence, excitation, normal and low temperature testing, PL, Raman, transmission, reflection, absorption and detector calibration. The possible configurations are endless. OmniFluo Fluorescence Systems can combine the PL and PLE in the same architecture.
Omnifluo fluorescence systems adopt high performance Omni-λmonochromator/spectrograph, high sensitivity single or multi-channel detector, single photon counting/lock-in amplifier technique. The standard for sensitivity is the signal-to-noise ratio calculated from a water Raman spectrum. Using this standardized test, our signal-to-noise ratio is 12000:1.

Fluorescence is the light emitted by matter after absorbing light or other electromagnetic radiation. When light is irradiated to some atoms, the energy of light makes some electrons around the nucleus from the original energy level to a higher energy level, that is, from the ground state to the 1st or 2nd excited singlet states. The 1st or 2nd excited singlet states are unstable, so the ground state will be restored. When the electron is recovered from the 1st excited single state to the ground state, the energy will be released in the form of light, that is to produce fluorescence.
