How does the Atomfair UV-VIS-NIR 739 handle the transition between UV-VIS and NIR measurement ranges?
The 739 uses two dedicated holographic gratings and two separate receiving systems, each optimized for either the UV-VIS (250–1100 nm) or NIR (1100–2500 nm) region. This dual-beam design enables seamless continuous scanning across the full 250–2500 nm range without the need for manual grating changes or performance compromises at the transition zone.
Can the Atomfair 739 be configured for diffuse reflectance measurements at specific angles?
Yes, the integrating sphere supports DRS (diffuse reflectance) mode, and optional reflection accessories are available at fixed angles of 5°, 15°, and 25°. These allow precise specular or directional reflectance analysis, making the instrument suitable for thin-film and surface characterization in semiconductor and materials research.
What are the system requirements and infrastructure needed to operate the Atomfair 739 spectrophotometer?
The instrument connects via a standard USB interface and does not require compressed air, cooling water, or other specialized lab infrastructure. The included software supports Chinese, English, and Russian languages and runs on typical Windows PCs, making integration into existing laboratory setups straightforward.
The Atomfair UV-VIS-NIR 739 Integrating Sphere Spectrophotometer is a dual-beam instrument covering 250–2500 nm with dual holographic gratings and dual receiving systems, enabling continuous scanning across UV, visible, and near-infrared bands. Its multi-mode measurement capability (reflection, transmission, absorbance, DRS) and optional angle-specific reflection accessories make it suitable for semiconductor and materials research applications requiring spectral flexibility.
Positive
- Broad spectral coverage: The 250–2500 nm range with dual holographic gratings ensures continuous scanning across UV, visible, and near-infrared bands, eliminating the need for manual grating changes during measurements.
- Multi-mode measurement capability: Supports reflection, transmission, absorbance, and DRS modes, with optional reflection accessories at 5°, 15°, and 25° angles, enabling versatile sample characterization in semiconductor and materials research.
Trade-offs
- Requires optional accessories: Full functionality depends on purchasing separate transmission, reflection, or DRS accessories, which are not included as standard and may add to the total cost of ownership.
- USB-only connectivity: The instrument relies solely on USB for communication, which may limit integration with older laboratory systems or require additional adapters for legacy setups.
