Industrial ComponentsCold Cathode X-ray Tube

Meiden cold cathode X-ray tubes use carbon nanostructures as emitters. While conventional hot cathode X-ray tubes use thermoelec heating cathodes via heater filaments as the electron source, cold cathode X-ray tubes use nano carbon electron availability as the source emitter. This makes the design compact, lightweight, and power saving while no warm-up period is needed making instant X-ray availab

Product Features

Operation Image
  • Compact and Lightweight
    No need for a heating element means a slim and compact shape.
    It is less than 50% the size of conventional products.
  • Low Power Consumption
    Power consumption is reduced because the cathode does not need to be heated.
    X-rays can be output even using dry batteries.
  • Instant Irradiation
    X-rays are emitted instantly upon power application, there is no cathode heater warm-up/stabilization period.
    Intermittent operation is possible because there is no standby time.
