1550 Series Glass X-ray Tube
Brand: Oxford Instruments | Category: Nanotechnology
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.

More from X-Ray Sources & Tubes
- 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.
- 1501 Series Glass X-ray Tube
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.
- 3000 Series 30kV X-ray Tube
Developed for high flux stability and long life, the 3000 Series potted tube is suited to continuous operation. It is encapsulated in silicone rubber and features a grounded cathode together with a low attenuation beryllium window, giving a low cost route to high spectral purity radiation. Targets are offered in tungsten, titanium, molybdenum, gold, iron, palladium, rhodium and silver, at anode powers from 6W to 27.2W depending on part number.
