Abstract: An apparatus (100) for laser induced breakdown spectroscopy (LIBS), comprising a sample chamber (112), a laser source (115) connected to an excitation optics assembly (120), the excitation optics assembly (120) connected to a first port (132) on the sample chamber (112), a collimator assembly (125) connected to a spectrometer (130), the collimator assembly (125) connect to a second port (135) on the sample chamber (112), and a first lens tube (150) positioned on the first port (132) and a second lens tube (155) positioned on the second port (135), the first lens tube (150) protecting the first port (132) connected to the excitation optics assembly (120) and the second lens tube (155) protecting the second port (135) connected to the collimator assembly (125) from particles emitted when a laser pulse from the laser source (115) ablates a surface of a target sample (145) and generates a plasma. The protection can alternatively be provided by a transparent partition (260) positioned between the first port (132) and the target sample (145).
