1550 Series Glass X-ray Tube

The 1550 Series X-ray tube is a 50kV, 50W X-ray tube designed for applications where high flux density and continuous operation are important.

Utilizing our highly stable, high intensity X-ray tube technology coupled with grid-controlled variable focus enables our 1550 Series X-ray tube to produce very small focal spots; this makes the 1550 Series ideal for most industrial inspection and non-destructive testing applications that require high resolution, including PCB assembly, battery, plastic, metal and mechanical parts inspection. Flexible and reliable, this unit is also highly suited for use with X-ray optics.

The 1550 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; this configuration is our popular Apogee 5500 Series packaged tube, which includes high voltage and filament connectors making it ideal for plug and play operation.
