Fluorescence analysis is a core characterization method in fields such as materials chemistry, biomedical science, optoelectronic materials, environmental detection, and food detection. Whether it is the luminous efficiency of fluorescent materials, the molecular energy level transition, the decay law of charge carriers, or the qualitative and quantitative analysis of trace substances, all rely on high-precision fluorescence spectroscopy data for support. Traditional single-steady-state testing equipment has limited functions, insufficient signal-to-noise ratio, and is unable to test fluorescence lifetime, making it difficult to interpret the dynamic luminescence mechanism of materials. Imported steady-state transient equipment is expensive, complex to operate, and has a long delivery cycle, which cannot meet the routine testing and industrial quality inspection requirements of domestic research, severely restricting the technical research and industrialization implementation in the field of fluorescence.
Based on the precision optoelectronic testing track, Saifan Optoelectronics has deeply cultivated fluorescence detection and spectral analysis technologies and has launched a fluorescence spectroscopy testing system. It integrates steady-state spectroscopy testing, transient lifetime testing, quantum yield analysis, and spectral correction analysis, with ultra-high signal-to-noise ratio, wide spectral coverage, non-destructive detection, and modular expansion. It completes the comprehensive performance characterization of various fluorescence samples in one step, providing standardized, traceable, and highly accurate complete solutions for cutting-edge scientific research innovation, material process iteration, and industrial precise detection.
Steady-state and transient integrated testing, comprehensive analysis of fluorescence performance
Different from traditional single-function testing equipment, this system realizes integrated testing of steady-state and transient modes, taking into account both static luminescence parameters and dynamic decay mechanism analysis, fully covering the core requirements of fluorescence characterization. The steady-state mode can accurately collect excitation spectra, emission spectra, fluorescence intensity, characteristic peak positions, half-widths, integrated light intensities, fluorescence quantum yields, etc., accurately completing qualitative analysis of materials, concentration calibration, and luminescence efficiency assessment, suitable for the basic characterization and quantitative detection of various fluorescence materials.
The transient time-resolved mode can accurately capture the dynamic decay process of fluorescence and phosphorescence, outputting high-precision fluorescence lifetime data, deeply analyzing molecular excitation state transitions, carrier recombination dynamics, defect state evolution laws, effectively distinguishing instantaneous fluorescence from delayed fluorescence characteristics, perfectly adapting to advanced research scenarios such as mechanism studies and material modification analysis, breaking through the technical bottleneck where traditional equipment can only measure intensity but cannot measure dynamic lifetimes.

Combined with dual monochromators for precise spectral division and multi-level filter noise reduction design, it can accurately select excitation light and emission light, completely eliminating stray light and scattered light interference, purifying the test signal from the source of the optical path, eliminating excitation light crosstalk and spectral distortion problems. Whether it is high-brightness fluorescence samples or extremely weakly emitting samples, it can ensure the authenticity and repeatability of spectral data.
Ultra-high sensitivity detection, ultra-low signal-to-noise ratio capture of weak fluorescence signals
For the testing difficulties of low-concentration trace samples, weakly emitting materials, and trace biological samples, the system is equipped with a high-sensitivity photodetection module, combined with single photon counting and lock-in amplification and noise reduction technology. The overall signal-to-noise ratio performance is excellent, capable of accurately capturing weak fluorescence and ultra-long-lifetime phosphorescence signals that traditional equipment cannot identify, with a detection limit reaching the level of research-grade. The entire testing adopts non-contact non-destructive detection mode, without damaging the sample structure or destroying the sample activity, suitable for repeated testing of samples, dynamic monitoring of performance changes, and applicable to precious scientific research samples, biological active samples, and precision film device testing scenarios.
The equipment is compatible with various forms of samples such as solids, liquids, powders, and films. No complex pre-treatment is required, and high-precision spectral collection can be completed quickly. This completely solves the industry pain points of traditional fluorescence equipment, such as high noise, weak signal, data drift, and poor repeatability.
