Abstract
An analysis system (e.g., LIBS) includes a laser source generating a laser beam, a movable optic configured to move said laser beam to multiple locations on a sample, and a spectrometer responsive to photons emitted by the sample at those locations and having an output. A controller is responsive to a trigger signal and is configured in a moving spot cycle to adjust the moveable optic, activate the laser source sequentially generating photons at multiple locations on the sample, and process the spectrometer output at each location.
Claims32
An analysis system comprising:
- a laser source generating a laser beam;
- a movable optic configured to move said laser beam to multiple locations on a sample;
- a spectrometer responsive to photons emitted by the sample at said locations and having an output;
- and
- a controller, responsive to a trigger signal, and configured in a moving spot cycle to:
- adjust the moveable optic,
- activate the laser source sequentially generating photons at multiple locations on the sample,
- process the spectrometer output at each location, and automatically terminate the moving spot cycle based on the spectrometer output if the spectrometer output indicates the sample is homogeneous.

An analysis system comprising:
- a laser having an output beam directed at a sample;
- a moveable optic configured to sequentially direct focused laser energy to multiple locations on a sample;
- a spectrometer outputting intensity data from the sample;
- and
- a controller system responsive to the spectrometer and configured to:
- initiate a focusing cycle wherein the laser is energized, the spectrometer output is analyzed, and the laser beam is adjusted until the spectrometer output is optimized resulting from a laser beam focused on the sample, and
- initiate a moving spot cycle wherein the movable optic is adjusted and the spectrometer output is analyzed for multiple locations on the sample.
