The Atomfair-RMS-739 contains an active visible-wavelength excitation laser whose collimated emission path must remain guarded while personnel perform alignment or measurement operations near its optics. Reliable spectral results depend on preserving focus-travel clearances and supplying illumination-system power within its labeled operating voltage range.
- Laser exposure control: Prevent direct viewing of apertures along the excitation beam path whenever any acquisition sequence keeps emitted radiation active.
- Power-input conformity: Connect adaptively powered illumination components only to an alternating-current supply within their accepted wide-voltage input range.
- Objective-to-sample clearance: Confirm that focus-travel limiting devices are engaged before advancing any objective toward a mounted specimen.
Place a supported specimen on the mechanical stage, select an appropriate objective lens, and lock optical focus before starting any emission-enabled acquisition sequence. Complete these actions chronologically whenever preparing wavelength-based or wavenumber-based Raman measurements.
Required Equipment: Confocal micro-Raman spectrometer, Safety eyewear suitable for visible-wavelength lasers, Sample-stage positioning controls
What is the minimum feature size that the Atomfair-RMS-739 can resolve in confocal Raman mode?
The Atomfair-RMS-739 can resolve features as small as 2 μm in diameter, as specified by its microscope optical system equipped with an infinite chromatic aberration correction system. This capability is enabled by the 100x objective and the confocal design, ensuring micro-sample compatibility for small-dimension analysis.
Does the Atomfair-RMS-739 support both wavelength and wavenumber Raman shift display?
Yes, the instrument features dual detection modes that allow flexible selection between wavelength (nm) and wavenumber (cm⁻¹) display, catering to different testing requirements as stated in the product description. This flexibility is essential for users who need to report Raman shifts in the conventional wavenumber scale for comparability across instruments.
How does the focusing mechanism of the Atomfair-RMS-739 contribute to measurement reproducibility?
The coaxial coarse and fine adjustment system provides a fine adjustment precision of 0.002 mm, with a coarse adjustment stroke of 30 mm. Additionally, the instrument includes a tightness adjustment device and an upper limit stop to maintain stable focus over repeated measurements, ensuring reproducible data collection for micro-sample analysis.
The Atomfair-RMS-739 is a 300mm focal length confocal micro-Raman spectrometer with a 532nm 100mW laser, 1200 lines/mm grating, and 2μm minimum measurement diameter, designed for high-resolution spectral analysis in teaching and research environments.
Positive
- Confocal design with 2μm spatial resolution: The infinite chromatic aberration correction system and 2μm minimum measurement diameter enable analysis of micro-scale samples, critical for heterogeneous materials and small-volume specimens.
- Dual detection modes and polarization analysis: Wavelength and wavenumber detection modes, combined with polarization performance analysis, provide comprehensive spectral information for advanced materials characterization.
Trade-offs
- Fixed 532nm excitation wavelength: The 532nm laser limits resonance Raman enhancement and may induce fluorescence in certain samples, potentially reducing spectral quality for some material classes.
- Requires stable optical alignment and calibration: The 0.2nm wavelength accuracy and repeatability demand periodic calibration with standard references, and the adjustable slit and focusing mechanisms require skilled operation to maintain optimal performance.
