The FUSIONS 10.6 Laser Stepped Heating System is configured for 40Ar-39Ar geochronology analysis of trace minerals. Used in conjunction with a noble gas mass spectrometer, this system provides for the targeting and controlled (stepped) heating of mineral sample (including feldspars) sections and grains to the fusion point. The beam delivery system and laser are suspended such that the sample chamber (customer furnished) can remain stationary, obviating the need for flexible HV extraction tubes.

Fusions

The FUSIONS 10.6 has the capacity to irradiate sample surface areas up to 6.0 mm in diameter using a field-proven, RF excited, sealed CO2 laser that can be continuously adjusted in output power to >55W. The beam delivery is optimized for maximum repeatability.

Productivity

FUSIONS 10.6 is a high performance, turnkey solution that, when interfaced with a computer controlled inlet system and software, enables the sampling of bulk materials in high capacity, multiple well sample chambers and in-situ probing of features within larger mineral samples.
The system electronics are configured to facilitate interfacing with inlet systems via input/output (I/Os) actuation for external software control and seamless, automated operation.

Performance

FUSIONS 10.6 features simultaneous viewing of the sample through the color, CCD camera, which is coaxial with the laser beam, for precise targeting and temperature control. Fiber optic ring light illumination of the sample eliminates shadows, dark zones and clipping of the light source by the sample chamber.
The entire laser, video microscope and beam delivery assembly “travels” over the user’s sample chamber (not supplied), which remains stationary. This obviates the need for flexible couplings resulting in higher reliability and lower blanks.

FUSIONS 10.6 is equipped for the addition of an (optional) optical pyrometer that measures sample temperature within the area irradiated by the laser beam.

The camera, pyrometer and laser have independent optical alignment components permitting the performance of each device to be optimized for peak performance. This unique design results in superior image sharpness, heating uniformity and measurement.

FUSIONS.810 DIODE LASER FUSIONS AND STEPPED HEATING SYSTEM for 4He/3He thermochronometry with temperature measurement

The Fusions.810 Laser Stepped Heating System is configured for 4He 3He thermochronometry (30W). Used in conjunction with a noble gas mass spectrometer, this system provides for the targeting and controlled, stepped-heating of mineral samples including rocks, sections, grains and micro-furnace packages to the fusion point.

Fusions.810

The Fusions.810 has the capacity to irradiate sample surface areas ranging from <0.4 mm to 6.0mm in diameter using a field-proven, near-IR (810nm) diode laser that can be continuously adjusted in output power. The beam delivers uniform heating of samples and repeatable results.
Its near-IR 810nm diode laser() as it couples more efficiently with platinum, palladium and other foils commonly used in micro-furnaces than CO2 lasers, for total fusions. The 810nm wavelength transmits through quartz, sapphire and BK-7 sample chamber windows, obviating the need for costly ZnS and ZnSe windows used with CO2 laser based systems.

Performance

Fusions.810 is equipped with pyrometer to measure temperatures from 300 to 2000degrees C. All other features and functions are identical to the FUSIONS 10.6.
