1501 Series Glass X-ray Tube

The 1501 Series X-ray tube is a 50kV, 50-75W X-ray tube designed for applications where high current, high flux density and continuous operation are important.

Utilizing our highly stable and high intensity X-ray tube technology, the 1501 Series X-ray tube is ideal for medical imaging, XRF applications and most industrial inspection and non-destructive testing applications that require high resolution, including PCB assembly, battery, plastic, metal and mechanical parts inspection.

The 1501 Series X-ray tube can also be supplied in a stainless steel, lead-lined package that is filled with dielectric oil that enables the unit to provide maximum X-ray shielding and heat dissipation.

The 1501 Series was designed in response to the need for higher current coupled with lower operating potentials.

The 1501 Series X-ray tube is available in a wide range of spot sizes, targets and price points to meet your needs.
