Abstract
An X-ray analysis apparatus includes a scanning unit (1) with an X-ray source (3), a crystal holder (9) and an X-ray detection system (5) provided with an X-ray detector (7). The crystal holer (9) can be rectilinearly displaced in a fixed radiation pick-up direction (35) relative to the X-ray source (3). The crystal holder (9) and the X-ray detector (7) are mechanically coupled to one another via a plate (21) which can be driven by means of a motion mechanism. The X-ray source (3), the X-ray detector (7) and the crystal holder (9) remain positioned on a Rowland circle (11) during the displacement. The motion mechanism has a first guide (23) and a second guide (25). The drive direction of the first guide (23) encloses an acute angle .alpha. relative to the fixed pick-up direction (35).
