    Abstract: A spectrograph as disclosed includes a housing, wherein a wall of the housing includes first, second and third openings, an entrance slit located at the first opening and configured to direct light along a first light path portion in the interior of the housing, a dispersive element located at the second opening and configured to receive light from the entrance slit along the first light path portion and direct light along a second light path portion in the interior of the housing, a detector located at the third opening and configured to receive light from the dispersive element along the second light path portion. The detector can include first and second groups of light-sensitive regions. A cover can be positioned to separate the first group of light-sensitive regions from the light path, the second group of light-sensitive regions being exposed to the light path.

    Abstract: A novel device, method and systems disclosed managing the thermal challenges of LIBS laser components and a spectrometer in a handheld structure as well the use of simplified light signal collection which includes a bare fiber optic to collect the emitted light in close proximity to (or in contact with) the test material. In one example embodiment of the handheld LIBS device, a burst pulse frequency is 4 kHz is used resulting in a time between pulses of about 250 μs which is a factor of 10 above that of other devices in the prior art. In a related embodiment, an active Q-switched laser module is used along with a compact spectrometer module using a transmission grating to improve LIBS measurement while substantially reducing the size of the handheld analyzer.
