Standard Tungsten Filaments
Web Link

EMS rebuildable tungsten filaments feature a rigid attachment of the filament to post, minimum tip radius and polished ends. Rebuilding service.

Lanthanum Hexaboride (LaB6) Cathodes Denka and Kimball Physics
Web Link

SEM and TEM LaB6 and CeB6 cathodes with extended life, high brightness, and exceptional stability from Kimball Physics, Denka and Applied Physics.

Applied Physics Lanthanum and Cerium Hexaboride Cathodes
Web Link

Lanthanum hexaboride (LaB6) and cerium hexaboride (CeB6) provide more beam current at a smaller spot for a brighter and longer lasting cathode.

Electron Microscope Filaments / Cathodes

Ted Pella, Inc. Web Link

Tungsten, LaB6 and Thermal Field Emission (TFE) cathodes and filaments for all types of SEMs and TEMs. EM Tungsten filament rebuilding services.

P-47 powder, YAP, and YAG SEM Scintillators

Electron Microscopy Sciences Web Link

YAP (Yttrium Aluminum Perovskite) and YAG (Yttrium Aluminum Garnet) scintillators for scanning electrons microscopes offer very fast response time and withstand well to the bombardment by electrons or ions far better than plastic or phosphor scintillators. P-47 scintillators have a high signal output and a good working life. Light pipe scintillators are available in optical quality quartz and optical grade acrylic.
