Fusion heating and electrical systems transform a standard TEM or SEM into an in situ laboratory. Our new product combines heating, electrical and electrothermal analysis and uses advanced holder and E-chip technology that provide ultra-high stability and accuracy. With Fusion, you can see samples under real-world conditions at atomic resolution and produce more results in less time.

Fusion combines a new low-power E-chip technology with holders constructed using special alloys to dissipate heat, resulting in minimal displacement and drift during heating. Fusion’s proprietary ceramic heating technology integrates the heater and the sample support into a single thin film with temperature uniformity that exceeds 99.5%.

The fundamental challenge facing electrical experiments in the TEM or SEM is the very low current required to characterize nanoscale samples. Fusion provides single digit picoamp measurements with sensitivity into the attoamps.  With over 30 different low-parasitic electrical E-chip variations, there is a sample support for every application.

Fusion Electrothermal E-chips feature a silicon carbide heater with tungsten electrodes that enable researchers to perform heating/electrical biasing experiments at high temperatures. The full features and specifications of the Fusion heating and electrical modes are combined with a single easy-to-use software interface.

Control your experiments with powerful, intuitive Clarity software. Program electrical and/or thermal stimuli as waveforms or change parameters as you go. Observe data in real time with a visual user interface that plots your results, and use optional ImageSync software to synchronize images with the heating and electrical data.
