Mesofocus – closing the gap between Minifocus and Microfocus

Until today, there were two kinds of X-ray tubes state of the art for industrial CT.

Until now, industrial computed tomography (CT) relied on two primary X-ray tube technologies: sealed Minifocus tubes and open Microfocus tubes. Minifocus tubes offer high power output and robust stability, making them ideal for high-throughput CT scanning in production environments. However, their large focal spot size limits resolution, reducing their effectiveness for fine-detail inspection.
In contrast, Microfocus tubes deliver exceptional resolution for high-precision CT imaging, but they lack the penetration power needed for dense materials and require more frequent maintenance due to their open design.
The new Mesofocus X-ray tube technology bridges this gap by enabling 450 kV industrial CT scanning with focal spot sizes as small as 63 microns. This results in significantly improved CT resolution and defect detection capabilities. For comparison, a traditional 450 kV Minifocus tube has a focal spot around 400 µm, offering roughly 6.5 times less resolution.

Depending on your application—whether inspecting large, dense parts or requiring high-resolution imaging—Mesofocus CT technology offers the ideal balance between penetration power, resolution, and maintenance efficiency, making it a powerful solution for modern industrial inspection.
