CO2 Spectrum Analyzer The CO2 Spectrum Analyzer is a unique grating spectroscope which simultaneously displays all the lasing transactions of a CO2 laser. It is calibrated both in wavelength and rotational line designation to permit easy identification of 140 possible laser transitions between 9.1 and 11.3 µ. These transitions are visually displayed through the use of a UV excited thermal sensitive screen which darkens in the area struck by the IR laser beam. The spectrum analysis screen has a response time of 1/4 seconds and permits the instrument to resolve all the CO2 rotational lines. The Model 16-A is light, portable and can easily be introduced into laboratory setups. Wavelength Scale This is a portion of the wavelength scale shown at full size. The upper calibrations are CO2 rotational line designations and the lower scale is the wavelength in microns. The thermal sensitive screen in the center displays the lasing wavelengths as a dark line. The wide sensitivity range of the sp
