The AQ6374 offers faster measurements and a purging feature (to minimize the influence of water-vapor absorption on spectral measurements) for general-purpose optical testing over the 350- to 1,750-nm range.
A significant effort was made to eliminate the intense atmospheric water-vapor absorption present in the THz region, and the etalon or standing-wave structure, which often limits sensitivity.
