SEM Single-Crystal LaB6 Electron Source

Description

Addressing the extreme requirements of desktop SEM for compactness and high imaging performance, Yifeng Electronics offers a pre-aligned electron gun assembly combining a Wehnelt grid, micro-aperture anode, and micro-tip La/CeB6 cathode. The modular electron gun design achieves precise coaxial alignment at the factory, allowing users to obtain an ideal coaxial beam spot without complex alignment procedures—truly 'plug-and-play'—significantly reducing equipment downtime and after-sales maintenance costs.
