What slit width should be used to achieve the ≤0.2 nm resolution on the Atomfair-MGS-739?
The ≤0.2 nm resolution is specified at a slit width of 0.2 mm and a wavelength of 550 nm. The slit is continuously adjustable from 0 to 2 mm with an indication accuracy of 0.01 mm, so operating with a 0.2 mm slit at 550 nm delivers the stated resolution. Adjusting the slit width trades resolution against light throughput for different measurement needs.
What role do the 320 nm and 500 nm cut-off filters play in fluorescence measurements with this spectrometer?
The included 320 nm cut-off filter blocks excitation light below 320 nm, and the 500 nm filter blocks light below 500 nm, allowing selective detection of longer-wavelength fluorescence emission. These filters are essential for separating weak fluorescence signals from scattered excitation light, directly supporting the fluorescence spectroscopy measurement application listed for the instrument.
The Atomfair-MGS-739 combines a 302.5mm focal length monochromator with a PMT detector and 1200L/mm grating, delivering ≤0.2nm resolution and 200-800nm scanning for absorption, emission, and fluorescence spectroscopy. Its 20kg mass and 0-2mm continuously adjustable slit require stable optical bench mounting and careful handling, while the included 320nm and 500nm cut-off filters extend dynamic range for UV-visible applications.
Positive
- High spectral resolution: With a 302.5mm focal length and 1200L/mm grating, the instrument achieves ≤0.2nm resolution at 550nm (0.2mm slit), enabling fine spectral feature discrimination for gas, liquid, and solid analysis.
- Integrated software suite: The included specialized software supports four fundamental arithmetic operations, spectral smoothing, data storage, and printing, facilitating quantitative analysis and documentation without external processing tools.
Trade-offs
- Heavy benchtop footprint: At 20kg and 370mm×260mm×170mm, the unit requires a dedicated optical bench or reinforced lab bench, and its mass complicates repositioning or field deployment.
- Narrow spectral range: The 200-800nm scanning range limits use to UV-visible applications; near-infrared or longer-wavelength measurements are not supported without additional hardware.
