High voltage power supplies for SEM / MASS

High voltage power supplies for SEM(Scanning Electron Microscope)

SEM is a technology to observe microscopic world using electron beams accelerated by high voltage power supply.
If the voltage for acceleration and biasing is not stable, the depth for electron incidented to specimen would be also unstable, and the image would be unfocused.
So the stability of high voltage power supply is one of the most important factors for SEM to realize high resolution.
Matsusada Precision lines up high stability, high temperature coefficient, and low ripple power supply ideal for SEM application.
Compact power supply with accelerator, bias, and filament supply are all in one is also available.

High voltage power supplies for MASS (Mass Spectrometer)

Mass spectrometry use ion beams for detections and measurements, therefore usually high voltage power supply for MASS Spectrometry requires quite high stability.
For example for TOF-MS(Time-of-flight mass spectrometer), one of the most popular mass spectrometry method, if the stability of accelerator power supply is poor, the energy of acceleration will be different every time you make the measurement. Naturally precise measurement is not expected with unstable power supply.
Lineups of Matsusada Precision MASS power supplies of high stability, greater temperature coefficient and lowest ripple noise offer you the better result.
