SPECIALIZED HIGH-VOLTAGE POWER SUPPLY FOR SCANNING ELECTRON MICROSCOPE (SEM)
Low Noise High Voltage Power Supply
- Output voltage for accelerating: 0 to -15 kV or -30 kV
- Output voltage for biasing: 0 to +3.5 kV
- Output power for filament: 15 W max
- High reliability design and elaborated protections
The exclusive design for bringing out the performance of an electron gun to the maximum!
This high-voltage power supply unit is for the electron gun of a Scanning Electron Microscope (SEM).
It incorporates a beam accelerator power supply, wehnelt cylinder bias power supply, and filament power supply, with the bias power supply and filament power supply floating on the acceleration voltage.
Not only tungsten filament-type thermionic emission guns and lanthanum hexaboride (Lab6) emission guns, but also Schottky-type electron guns can be supported by adding an optional power supply for suppressors.
We are also available for consultation on customization and custom-made products for your electron gun. Please feel free to contact us.
