An X-ray texture goniometer equipped with a vertical Soller slit and a monochromator in the secondary beam in combination with Cu radiation is found to be useful for pole figure measurements on different materials, e.g. Al and Fe, as well as for low incident beam angle measurements on thin coatings. The obtained ODF's are less sensitive to errors in the procedure used for background correction of the pole figures than obtained with the classical setup used for pole figure measurements. The reason for that is the drastically ameliorated Intensity/Background (I/B) ratio by the use of the monochromator. Examples for cold rolled Fe and Al are presented. One of the merits of the new setup is that pole figures of Al, Cu, Ti, Fe can all be measured by using Cu Kα radiation, thus avoiding frequent and time-consuming exchanges of X-ray tubes.
