Fluorescence lifetime measurement spectrofluorometer SP-F97 series

compact

Product overview
SP-F97, SP-F97pro and SP-97xp are bench-top fluorescence spectrometers delivering excitation–emission measurements across 200–900 nm. The instruments combine a double-grating monochromator, excitation dual-beam ratio monitoring and Hamamatsu xenon light source plus photomultiplier detection to support sensitive, fast and reproducible fluorescence analysis for R&D and routine laboratories.

Key features

• Detection sensitivity: water Raman peak S/N ≥150 (SP-F97/SP-F97pro) or ≥200 (SP-97xp).
• Scanning speed: up to 48000 nm/min for rapid 1 s classical spectra and ~1 min for high-quality 3D scans.
• Spectral range: excitation and emission continuous range 200–900 nm via double-grating monochromator.
• Bandwidth options: selectable excitation/emission bandwidths — 2/5/10/20 nm (model-dependent).
• Monitoring: excitation dual-beam ratio monitoring for stable signal acquisition.
• Optical gate: programmable optical gate for samples with light-reactive or unstable fluorescence.
