What are the spectral resolution and stray light specifications of the Atomfair-MFS-739 mini spectrometer, and how do they impact performance in low-light measurements?
The Atomfair-MFS-739 delivers a spectral resolution of 2 nm with a wavelength accuracy of ±1 nm, and its stray light is specified at <0.05% @600 nm. These specs, combined with a signal-to-noise ratio of 250:1 and a 2048-pixel linear CCD detector, make it well-suited for precise low-light measurements where minimizing optical noise is critical.
How does the Atomfair-MFS-739 interface with a computer, and what is required for data acquisition?
The spectrometer connects directly to a computer via a USB2.0 interface and requires the installation of supporting software to form a complete measurement system. It uses an SMA905 fiber optic connector for input and has no moving parts, eliminating the need for frequent recalibration during routine data acquisition.
Does the Atomfair-MFS-739 require frequent recalibration, and what are its power consumption and portability characteristics for field use?
The instrument has no moving parts, which significantly reduces drift and eliminates the need for frequent recalibration, enhancing usability in field environments. It consumes only 120 mA at 5 VDC and weighs 200 g with dimensions of 64 mm × 89 mm × 36 mm, making it highly portable for on-site spectral analysis.
The Atomfair-MFS-739 Mini Fiber Optic Spectrometer combines a crossed Czerny-Turner optical path with a 2048-pixel linear CCD and 2 nm resolution across 350–1000 nm, delivering a compact, calibration-free solution for chemical, photometric, and fluorescence analysis. Its SMA905 interface and USB2.0 connectivity enable straightforward integration with standard fiber-optic accessories, though the 25 μm slit and 12-bit ADC impose inherent sensitivity and dynamic-range limits.
Positive
- Compact, calibration-free design: The asymmetric crossed Czerny-Turner optical path with no moving parts eliminates the need for frequent calibration, reducing maintenance and improving long-term operational stability in laboratory settings.
- Broad spectral range and resolution: Covering 350–1000 nm with 2 nm resolution and ±1 nm wavelength accuracy, the spectrometer supports diverse applications including chemical analysis, photometric measurement, and fluorescence spectroscopy without requiring multiple detectors.
Trade-offs
- Fixed slit limits sensitivity: The 25 μm entrance slit is fixed, constraining light throughput and potentially reducing signal strength for low-intensity or fluorescence measurements, which may require external fiber-optic or probe optimization.
- Moderate dynamic range and SNR: With a 12-bit ADC and 250:1 signal-to-noise ratio, the instrument offers limited dynamic range compared to higher-end spectrometers, which may affect quantitative analysis of weak or highly absorbing samples.
