LIBSpector
SETUP
The LIBSpector (LIBS inspector) is a versatile and compact sample chamber for the spatially resolved analysis of solid, liquid and gaseous materials by means of laser-induced breakdown spectroscopy (LIBS). In combination with a high-resolution, optical fiber coupled echelle spectrometer from the ARYELLE and DEMON series and a suitable LIBS laser for plasma ignition the LIBSpector is part of the modular LIBS analyzer LIBSlab.
It features online video monitoring and a motorized XYZ stage for qualitative and quantitative sample mapping which is controlled by the supplied joystick. The LIBS laser head can be built in the sealed laser class 1 housing with laser protection window for observation, door interlock and exhaust flange provide a safe use. No additional laser safety precautions are therefore required at installation site. The optimized optical setup of the model µ-LIBSpector provides a highly reduced laser spot size on the sample surface. Several sample holders for solid, liquid and gaseous substances provide universal application capability and can be adapted to individual customer requirements.
