Abstract
Implementations are described herein for isolating mirrors and/or other potentially-vulnerable components of multi-pass optical systems from samples being analyzed, while mitigating interference and/or reduction in optical power. In one implementation, an apparatus may include: an optical cell with one or more passages, the one or more passages provided for introducing a sample into an interior of the optical cell for analysis and for removing the sample from the interior; a first mirror with a first reflective surface that faces the interior of the optical cell; one or more additional mirrors with one or more corresponding additional reflective surfaces that face the first reflective surface of the first mirror; and a wedge-shaped optical element positioned between the first mirror and the interior of the optical cell.
