Abdelbagi, Abdelrazig Mohamed; Kamal, Maha


The main objective of this study was to assess the molecular simulation of the design of carbon dioxide (CO2) and to construct infrared optical filters for the transmission and absorption of the CO2 laser and the emission of gaseous CO2 radiation. Semiconductor compounds used to determine the wavelength of infrared transmission and absorption infrared radiation (IR) to produce an IR filter for laser production and gas emission using the Fourier Transform infrared spectrometer (FT-RI) for research purposes. Carbon dioxide molecule simulation has been used based on Hyper 6 simulation programme in potential energy, and kinetic energy, which measures the infrared radiation spectrum. Infrared filters are constructed from the compounds of a semiconductor of Zinc Sulfide supplied (ZnS), Aluminum Oxide (Al2O3), Magnesium Oxide (MgO), Lead (II) Sulfide (PbS), and Potassium Chloride (KCl). The data used for evaluation of the optical elements in the IR region based on the transmission and absorption of radiation intensity effective for wavelength detection. The assessment of the detection is indicating transmission and absorption of the wavelengths of CO2 laser and CO2 gas molecule under investigation. This study has identified the approach of the result of transmission and absorption of the peak intensities of 10.6, 2.7, 4.3 and 15μm of CO2 laser and gas radiation emission of the filters in the IR region. The findings of this study have a number of important applications in the IR radiation region.
