June Spectra of the Month: Plasma Measurements
 
|||| ||||

In June, the Avantes engineering team used Optical Emission Spectroscopy (OES) to collect spectral measurements of Helium and Hydrogen in their plasma state in high-energy gas lamps using the high-resolution CMOS based miniature spectrometer AvaSpec-Mini4096-MKII.

With the amazing resolution of the new 4096 pixels AvaSpec-Mini, the atomic spectral lines of Hydrogen and Helium were recorded at FWHM (Full-Width, Half-Max) values averaging around 0.15nm. We recorded Helium peaks at 447, 471, 492, 501, and 587 nm. Peaks for Hydrogen were recorded at 410, 433, and 486 nm.

The AvaSpec-Mini4096CL was configured with a 1200 lines/mm grating for a wavelength range of 380nm to 618nm. This instrument included options for a detector collection lens DCL-UV/VIS-200, and order sorting filter OSF-305, with a 10µm slit installed. To obtain measurements, the team optically aligned a collimating lens to the glowing plasma to collect photon counts.
