Abstract
An optical multi-pass cell (100) including a sample cavity (109) is provided. The cell (100) also includes first and second end mirrors (103, 104) positioned within the housing (101). The mirrors (103, 104) are configured to reflect a beam of light directed at one of the first or second end mirrors (103, 104) off-axis from the optical axis (113) one or more times between the end mirrors (103, 104) through the sample cavity (109) at a first distance from the optical axis (113) to create a first beam pattern (330). The cell (100) also includes one or more relay minors (220) positioned to intercept reflect the beam of light such that at least a second beam pattern (331) is created between the end mirrors (103, 104) at a distance from the optical axis (113) different from the first distance of the first beam pattern (330).
