Patent ID: 7738630

Claim:
An x-ray analysis apparatus for illuminating a sample spot with an x-ray beam, comprising: an x-ray tube having a source spot from which a diverging x-ray beam is produced, the source spot requiring alignment along a transmission axis passing through the sample spot; a first housing section to which the x-ray tube is attached along a first axis thereof, the first housing section including adjustable mounting features for adjustably mounting the x-ray tube therein such that the source spot coincides with the first axis, the first housing section further including mating surfaces aligned to the first axis; a second housing section having a second axis coinciding with the transmission axis, and mating surfaces aligned to the second axis; and at least one x-ray optic attached to the second housing section for receiving the diverging x-ray beam and directing the beam toward the sample spot, the at least one x-ray optic requiring alignment along the transmission axis; the first housing section and second housing section being matable along their respective mating surfaces to thereby align the first and second axes with the transmission axis, thereby aligning the source spot, x-ray optic, and sample spot.
