OmniFluo 900 Series Fluorescence Spectrometer has two series of products: steady fluorescence spectrometer and transient fluorescence spectrometer. The main components of this system are high-performance Omni-lambda monochromatic/spectrometer, high-brightness multicolor light source and multi-wavelength monochromatic light source, high-sensitivity single photon detector and large-capacity sample chamber. With carefully optimized excitation and emission light path design, the sensitivity of fluorescence signal detection is significantly improved, and the Raman signal-to-noise ratio of pure water can reach more than 10,000: 1.
