• Electrostatic Chucks (ESC)
• And more…

Spellman's Electron Beam Module (EBM) range offers solutions capable of driving most electron emitters, including thermionic emitters such as Tungsten and LaB₆, as well as field emissionsources including Cold Cathode and Schottky emitters. These systems provide integrated outputs for acceleration voltage and emitter drive, while many models also include the high-voltage outputs required to power the multiple detectors used in modern electron microscopes.

Spellman's Focused Ion Beam (FIB) range incorporates high-stability accelerator voltages with floating outputs to drive traditional gallium ion and plasma sources in a compact 19-inch rack solution. An additional Lens Rack is available, providing high-performance fixed or reversible polarity high-voltage lens supplies required to focus the ion column for demanding microscopy applications.

With Spellman's exceptional performance—including low ripple, low micro-discharge, and ppm-level stability—customers can achieve outstanding image quality, resolution, and long-term system reliability.
