Abstract
A handheld LIES device includes a laser source for generating a laser beam, a spectrometer subsystem for analyzing a plasma generated when the laser beam strikes a sample, and a nose section including an end plate with an aperture for the laser beam and for receiving plasma radiation and an optic spaced from the end plate defining with the end plate a cavity therebetween. An atmospheric purge subsystem includes an air pump with an intake exposed to the atmosphere and a conduit connected to the air pump providing an atmospheric gas mixture to the nose section cavity to purge the cavity of contaminants and keep the optic clean as the atmospheric gas mixture exits the cavity through the end plate aperture.

A handheld LIBS device with atmospheric purge, the device comprising:
- a laser source for generating a laser beam;
- a spectrometer subsystem for analyzing a plasma generated when the laser beam strikes a sample;
- a nose section including:
- an end plate with an aperture for the laser beam and for receiving plasma radiation, and
- an optic spaced from the end plate defining with the end plate a cavity therebetween;
- and
- an atmospheric purge subsystem including:
- an air pump with an intake exposed to the atmosphere, and

A handheld LIBS method comprising:
- generating a laser beam through a transparent optic and an end plate aperture defining a cavity therebetween;
- analyzing a plasma generated when the laser beam strikes a sample;
- and
- while generating the laser beam, providing an atmospheric purge gas mixture to the cavity via an air pump with an intake exposed to the atmosphere and a conduit connected to the air pump providing the atmospheric gas mixture to the nose section cavity to purge the cavity of contaminants and keep the optic clean as the atmospheric gas mixture exits the cavity through the end plate aperture.
