Abstract

A mirrorless multiple path cell which can be efficiently used in the FIR is described. The device is based on the White cell and light pipe methods, and requires no setup even after cooling. It is shown how the system can be efficiently operated if certain geometrical conditions are maintained which ensure a uniform light energy distribution inside the cell. The optimization of some physical parameters is discussed, and it is shown that an effective absorption pathlength as long as 4 or 5 m can be obtained with a simple absorption cell which is 10 cm long. The FIR spectrum of CH4 obtained using the cell is presented.
