Abstract

The present disclosure provides a compact multi-pass absorption gas cell comprising a rectangular housing defining a chamber for receiving a sample to be analyzed, a light inlet positioned at a first end of the rectangular housing for introducing light beam into the chamber, a light outlet position at a second end of the rectangular housing, a first mirror component positioned at the first end comprising a first flat mirror and a first concave mirror array, and a second mirror component positioned at the second end comprising a second flat mirror and a second concave mirror array, wherein the light beam reflects multiple times between the first mirror component and the second mirror component and is refocused by the first concave mirror array and the second concave mirror array to achieve an optical path length for low absorption gas detection.
