1501 Series Glass X-ray Tube
Brand: Oxford Instruments | Category: Nanotechnology
Rated at 50kV and 50-75W, the 1501 Series answers the need for higher current at lower operating potentials while keeping high flux density and continuous operation. It serves medical imaging, XRF and industrial inspection or non-destructive testing that demands high resolution, covering PCB assembly, battery, plastic, metal and mechanical parts. A stainless steel, lead lined package filled with dielectric oil is available for maximum X-ray shielding and heat dissipation, and the series comes in a range of spot sizes and targets. Ultra-high vacuum held by the Oxford Instruments getter technology supports long tube life.

More from X-Ray Sources & Tubes
- 1550 Series Glass X-ray Tube
This 50kV, 50W glass envelope tube pairs Oxford Instruments high stability, high intensity technology with grid controlled variable focus, so it produces very small focal spots. That makes the 1550 Series a good match for industrial inspection and non-destructive testing that needs high resolution, including PCB assembly, battery, plastic, metal and mechanical parts inspection, and it also works well with X-ray optics. Supplied in a stainless steel, lead lined package filled with dielectric oil, the same tube becomes the Apogee 5500 Series packaged assembly with high voltage and filament connectors for plug and play operation. Long tube life follows from ultra-high vacuum maintained with the company's getter technology.
- 1500 Series Glass X-ray Tube
A 50kV, 50W glass envelope X-ray tube intended for work that needs high flux density and continuous running. Its high stability, high intensity tube technology suits medical imaging, XRF and most industrial inspection and non-destructive testing tasks that call for high resolution, including PCB assembly, battery, plastic, metal and mechanical parts inspection. The tube can also be supplied in a stainless steel, lead lined package filled with dielectric oil for maximum shielding and heat dissipation, effectively replicating the Jupiter 5000 Series packaged tube with its high voltage and filament connectors for plug and play use. Ultra-high vacuum maintained by the Oxford Instruments getter technology gives long tube life.
- OpenView Series Glass X-ray Tube
A 40 degree cone angle is what sets this tube apart, opening up a large field of view even when magnification is high. Oxford Instruments aims it at high resolution imaging in cabinet X-ray systems and other work that needs precision and clarity. An artifact-free beryllium window can be specified for low contrast imaging where background and subject densities sit close together, which brings soft tissue biopsy within reach. Ultra-high vacuum maintained with the company's getter technology supports long tube life.
