Oxford Instruments glass X-ray tubes are recognized for their performance and long life.
High flux and spot size stability make our X-ray tubes an ideal solution for demanding applications, such as those requiring continuous operation. The 90507 and other 1000 series tubes are uniquely designed with a very small isostatically focused spot for high resolution applications, such as mini C-Arm fluoroscopy. The robust electron gun assembly has been constructed for optimal use in integrated X-ray sources, where heat dissipation is an issue. Long tube life is achieved by ultra-high vacuum maintained with the Oxford Instruments unique Pin Flash getter. This tube operates in bi-polar mode.
