Abstract
A multiple-pass cell for mid-IR spectrometry that has been designed to oper ate in an evacuable environmental chamber is described. Using this new modi fied White arrangement, we can significantly increase the path length while keeping the spectrometric beam stable. An approximate expression that ties the number of reflections to the optimal signal-to-noise ratio in multiple -reflection cells is derived. (C) 1999 Optical Society of America.
