Next Generation Imaging Equipment using Nano-electrons
Scientia Concors Inc. (中和科学株式会社) is a world-leading company in nano-electron source technology using LaB6 (lanthanum hexaboride) nanowires.
This is a technology that has the ability to raise the performance of electron microscopes to the next generation level.
Conventional electron guns used in electron microscopes are low-cost, low-resolution thermal electron guns with tungsten filaments which account for 80% of the market, and the other choice, cold field emission guns (CFEG) with high-resolution tungsten needle emitters are very expensive because they require an extremely high vacuum.
The new CFEG with LaB6 nanowire emitter is compatible with a wide range of these types of electron microscopes and offers higher performance at a lower cost.
Compared to conventional CFEGs, it is 1/40th the size and 1/10th the cost.
This is the world’s smallest cold field emission gun.
The LaB6 nanowire CFEG is very small and also does not require an extreme high vacuum. Therefore, simply replacing a tungsten filament thermal electron gun with it can instantly achieve high resolution even with an affordable tabletop SEM (scanning electron microscope).
Furthermore, during the 5000 hours of testing, it was verified that there was no decay of the probe current. Not only is resolution improved, but also its lesser energy consumption resulting in a longer operating time.
It can also be incorporated into higher-end electron microscopes to achieve a variety of effects.
For aberration-corrected scanning transmission electron microscopes, it provides the highest spatial, contrast, and energy resolution.
In field emission SEM, noise reduction, fast mapping of EDX (energy dispersive X-ray analysis), and no probe current attenuation are achieved.
It combines the advantages of thermal electron emission filaments and cold field emitters while overcoming their respective weaknesses.
The world’s most advanced technology is here.
