The FLS FLS980-STM Fluorescence Spectrometer User Manual describes functions, performance specs, measurement principles, and step‑by‑step operating procedures.
The FLS980-STM is a steady‑state and time‑resolved fluorescence spectrometer capable of measuring liquid and solid samples. It offers steady‑state excitation/emission spectra, fluorescence lifetime from picosecond to millisecond scales, quantum yield using an integrating sphere, and anisotropy measurements with polarizers.
The manual provides detailed instructions for instrument setup, safety precautions, and measurement workflows for both steady‑state and transient fluorescence, including software operation, light‑source selection, slit adjustment, detector cooling, and data acquisition. This manual is written in Chinese.
| Spectral detection range | 200 nm – 1800 nm |
|---|---|
| Fluorescence lifetime range | ps to ms |
| Light sources | 350 W Xe lamp, microsecond flashing Xe lamp, single‑wavelength pulsed lasers (375 nm, 405 nm, 475 nm, 635 nm, 670 nm, 785 nm) |
| Slit width range | 0.02 nm – 18 nm |
| Maximum signal rate (microsecond Xe lamp) | ≤ 5 000 |
The sample chamber door must be open before the software is started.
Set the slit (Δλ) to its minimum of 0.02 nm before any light‑source change or sample adjustment.
The CO1 temperature must be below –20 °C before data acquisition can begin.
The signal rate should not exceed 5 000.
