SP-3200 UV-Vis-NIR spectrophotometer

SP-3200 UV-visible near-infrared spectrophotometer is a high-performance UV/VIS/NIR spectrophotometer. Equipped with built-in transmission, specular reflection and integrating sphere accessories, it can measure transmission and reflection spectra of various samples, including paint coatings, architectural glass, and semiconductor materials.

Instrument Features

1. Imported light source for longer life and better stability.

2. Dual imported detectors for the UV/VIS/NIR bands provide greater sensitivity to weak signals, reduced noise, and higher accuracy.

3. A dual-beam, dual-grating, and dual-detector optical system design reduces background interference, improves measurement accuracy, and achieves full spectral coverage of the UV, VIS, and NIR bands.

4. Control system: Computer-controlled instrument (including grating switching, filter switching, receiver switching, and wavelength scanning), automatic power-up calibration, and automated data acquisition and processing.

5. Seven selectable slit widths: 0.2nm, 0.5nm, 1.0nm, 2.0nm, 3.0nm, 5.0nm, and 7.0nm. Users can select any slit width based on their needs.
