We conducted optical modeling and constructed a multi-pass optical cell for human breath analysis by Tunable Diode Laser Absorbtion Spectroscopy (TDLAS) techniques. The cell comprises two concave cylindrical mirrors and achieves a 3.5 m optical path length within a $5 \times 5 \times 5 \mathbf{c m}^{3}$ volume, enabling its use in portable devices for examining human exhalation.
