Paper Abstract

The Los Alamos National Laboratory is building a Fourier Transform Spectrometer (FTS) that will be the most powerful and precise instrument of its kind in the world. The FTS will have a maximum resolution of 0.001 cm-1 when the light is double passed. The A/D con-verter will have a dynamic range of 22-bits and will acquire points at a rate of 40 KHz. A digital filter will be used to reduce the bandwidth of the data and will output data points at a rate of 4-5 KHz. Scan times will be typically 4-5 minutes for a high-resolution scan. The servo control will be accurate to 1-2 millifringes of 632.8 nm He-Ne laser light. The spectral range will be from 200 to 20 000 nm (500 to 50 000 cm-1). We will be able to ac-quire multiple scans to help improve the signal to noise.
