Abstract

A container (100) to be positioned in a ring-down optical cavity for containing a sample includes an outer surface having opposing first and second outer faces (112, 114) and an inner surface forming a void (120) for containing the sample and having opposing first and second inner faces (116, 118). The container (100) may include a first portion forming the first outer face (112) having a second index of refraction and a second portion forming the second outer face (114) having a third index of refraction. The container may be placed in an optical cavity including a medium. The first and second outer faces (112, 114) of the outer surface and the first and second inner faces (116, 118) of the inner surface are oriented so that the cavity-to-container interfaces and the container-to-sample interfaces of the container transmit and receive a light beam at an incidence angle approximately equal to the Brewster's angle of the respective interface.
