These superior cathodes are made using high quality ceramic disc, exact size contact pins and high grade tungsten filament wire. Special tools are used to produce the correct shape of the tungsten filament. They are precisely aligned and annealed in high vacuum to reduce stress in the filament. This will guarantee optimum stability, maximum brightness, longer lifetime and overall lower running costs.
Exclusive features:
- Minimum tip radius for coherent beam
- Rigid attachment of filament wires to post to increase stability
- Fully stress relieved for enhanced cathode lifetime
- Polished post ends
- Precise dimensions
- Better long term economy
