We have developed a spectral module for the selection of narrow characteristic spectral lines of isotopes in the ultraviolet Raman spectral channel. To allow resolving closely spaced isotope lines in the continuous input radiation spectrum, extremely high resolution λ / Δλ = 1000 is implemented. The total inverse linear dispersion at the output of the double polychromator (dλ / dl = 0.048 nm / mm) allows us to confidently separate the methane lines 283.31; 284.42 nm.
