Nonresonant cavity as a long path absorption cell.
We have constructed spherical specularly reflecting nonresonant cavities for use as absorption cells in far ir spectroscopy. A theory of their performance is developed and shown to be in agreement with experiment. An example is given of their use in a research program to ascertain the composition of water vapor. The essential advantage of these cells is that they give long pathlengths with high energy throughput.
