​​​​​​​​​Fusions Diode Stepped Heating SystemFu​sions .970 Diode Laser Stepped Heating System​

The Fusions Diode is a diode-laser based system for controlled heating of samples within micro-furnace packets to the point of fusion. The Fusions Diode enables the use of high capacity, multiple well, HV sample chambers and provides localized heating of samples in diffusion cells without the use of a furnace. This unique system features co-linear targeting, stepped heating and spot-on temperature measurements through a standard sapphire viewport.

Fusions Diode features simultaneous viewing of the sample via a color, camera that is coaxial with the laser beam for precise targeting and temperature control. Flood lighting of the sample eliminates shadows and dark zones caused by deep wells and when observing samples close to the edge of the viewport.

The Fusions Diode is equipped with an optical pyrometer that measures sample temperature within the area heated by the laser beam for spot-on measurements.​​​
