FP-8500 Spectrofluorometer Optimized for Research Measurements in the UV-visible Region

The FP-8500 has the highest sensitivity and optimal spectral accuracy with a wide range of accessories for maximum flexibility in experimental design. 


The FP-8500 spectrofluorometer has an optimized optical design for very low stray light and a dynamic range of up to 6.5 orders of magnitude. It is exceptionally sensitive with a Raman S/N ratio of 8,500:1 (RMS), which allows for fast measurements of samples with low level fluorescence. The high spectral resolution of 1.0 nm, automatic band-pass filters for exclusion of higher-order diffraction, and accurate spectral correction assures accurate measurements for the evaluation of advanced materials. The high-speed scanning enables fast measurements of 3D spectra and phosphorescence samples.


  • High intensity continuous output Xenon arc lamp
  • Energy monitoring of the excitation energy for stability
  • Shutter to protect samples until measurement
  • Stray light rejection filters
  • High sensitivity S/N 75,000:1 (RMS, water Raman)
