Abstract
A handheld LIBS spectrometer system features an optics stage moveable with respect to a housing and including a laser focusing lens. A laser source is mounted in the housing for directing a laser beam to a sample via the laser focusing lens. A detection fiber is mounted in the housing and is fixed relative thereto. A first mirror is fixed relative to the housing and includes an aperture for the laser beam. This mirror is oriented to re-direct plasma radiation for delivery to the detection fiber. A controller subsystem is responsive to the output of a spectrometer subsystem and is configured to control the laser source and the optics stage.
