A microfocus X-ray source is an X-ray tube with a focal spot size on the micrometer scale (microns). These sources are essential for high-magnification, high-resolution non-destructive X-ray inspection of industrial samples. Microfocus X-ray tubes are available in two main types: sealed and open. Tubes with even smaller, nanometer-scale focal spots are known as nanofocus X-ray sources. Conversely, those with larger focal spots are referred to as minifocus or millifocus. Some medical X-ray tubes are also designed to switch between a large and a small focal spot.
