A goniometer head, particularly for an X-ray diffractometer, is provided with a support which can be attached to the diffractometer and with parts, which can be adjusted in the x, y and z direction and which have an x and y slide, respectively, and appertinent x and y, respectively, adjusting lead screws. The part which is adjustable in the z direction is constructed to accommodate a sample holder. The support is made of plastic and has an upright section having a hole, which acts as the x slide and in which the x adjusting lead screw extends with a smooth central shank portion. A top part likewise made of plastic is fastened, by means of a snap-fit connection element, on the central shank portion of the x adjusting lead screw. The top part has a hole, which acts as the y slide and in which the y adjusting lead screw extends with a smooth central shank portion. Fastened thereto is a second snap-fit connection element for mounting the part which is adjustable in the z direction. |
