Abstract: A laser induced breakdown spectroscopy (LIBS) analyser (10) comprises an optical path P (shown by dashed lines P1 and dash-dot lines P2) and an automatic focus (or tracking) system (12). The optical path P focuses a laser beam emitted from a laser (14) onto a portion of sample S which is to be analysed by the analyser (10), and focuses radiation emitted by the sample S when irradiated by the laser beam to a detector (16). The automatic focus system (12) is capable of varying a length of the optical path P to maintain a constant spatial relationship (i.e. distance) between a focal point (18) of the laser beam and the sample S; as well as maintaining a constant instantaneous field of view (IFOV) of the detector (16) on the focal point of the laser.

Abstract: Un analizador de espectroscopia de plasma inducido por laser (LIBS) comprende una trayectoria optica P (mostrada por la linea de rayas P1 y la linea de rayas- puntos P2) y un sistema de enfoque (o seguimiento) automatico. La trayectoria optica P enfoca un rayo laser emitido desde un laser sobre una porcion de una muestra S que va a ser analizada por el analizador, y enfoca la radiacion emitida por la muestra S cuando es irradiada por el rayo laser a un detector. El sistema de enfoque automatico es capaz de variar una longitud de la trayectoria optica P para mantener una relacion espacial constante (es decir, una distancia) entre un punto de enfoque del rayo laser y la muestra S; asi como mantener un campo de vision instantaneo constante (IFOV) del detector sobre el punto focal del laser
