Abstract: A Raman gas analyzer for detecting carbon isotopologues with an excitation laser with a power of 5 W, generating at a wavelength of 532 nm, focusable in a waist of 7 μm using a lens with compensation for spherical aberration is presented. The signal is detected by a high-resolution spectrometer with a matrix cooled to -40° C. The program optimization of the system parameters is presented: focusing lens, cuvette windows.
