Multipass cell from IRsweep has a single circular mirror

The IRcell multipass cell for optical trace gas sensing, which consists of a single circular mirror, offers a 4 m optical path in a 30 ml sample volume, resulting in short gas exchange times. The single-piece construction makes the cell invariant to temperature changes. Applications include those requiring an optical path length of 1–5 m.
