F97 Fluorescence Spectrophotometer

Product Introduction
The F97 Fluorescence Spectrophotometer is a high-sensitivity analytical instrument designed for fluorescence measurement, spectral scanning, and quantitative analysis. It features a double-monochromator optical system, a dual-beam excitation light monitoring system, and a 150 W high-intensity xenon lamp to support stable optical performance and sensitive signal detection.
Equipped with a 1200 lines/mm concave grating and large-aperture aspheric mirrors, the F97 provides excitation and emission wavelength coverage from 200 to 900 nm. Its software supports multiple analytical functions, while rapid three-dimensional fluorescence scanning can be completed in approximately one minute under the specified operating conditions. A built-in automatic light-blocking door helps protect light-sensitive samples and improve measurement consistency.

Performance Features
• Double-Monochromator Optical System: Provides wavelength selection for excitation and emission measurements.
• Dual-Beam Excitation Monitoring: Monitors excitation light intensity to improve signal stability and measurement reliability.
• High-Intensity Xenon Lamp: Uses a 150 W xenon lamp to provide illumination across the specified spectral range.
• Wide Spectral Coverage: Supports excitation and emission measurements from 200 to 900 nm.
• Rapid 3D Fluorescence Scanning: Completes full three-dimensional spectral scanning in approximately one minute, according to the manufacturer.
• Adjustable Spectral Bandwidth: Offers four selectable bandwidth settings: 2, 5, 10, and 20 nm.
• High Sensitivity: Achieves a water Raman peak signal-to-noise ratio of at least 200 (peak-to-peak).
• Large Photometric Range: Displays fluorescence photometric values from 0.00 to 10,000.
• Automatic Light-Blocking Door: Helps minimize unwanted light exposure for photosensitive samples and supports consistent excitation timing.
• Flexible Software Analysis: Provides multiple analytical functions for different sample testing requirements.
• Convenient Data Export: Supports Microsoft Excel-compatible data and BMP image output.
• USB 2.0 Connectivity: Enables straightforward connection to a computer for data transmission and instrument operation.

Working Principle
The F97 Fluorescence Spectrophotometer measures the light emitted by a sample after excitation at a selected wavelength. The xenon lamp provides the excitation light, and the excitation monochromator selects the required wavelength. When the sample absorbs this energy, fluorescent molecules may emit light at longer wavelengths.
The emission monochromator separates the emitted light by wavelength, and a photomultiplier tube detects the resulting optical signal. The dual-beam excitation monitoring system tracks excitation intensity to help compensate for light-source fluctuations. The software processes the measured signal to generate fluorescence spectra and support quantitative analysis.
