Blanks ‐ the thin quartz plates industrially used for oscillators, nowadays produced at rates of millions per week ‐ need thorough controls of their properties. The most important of them, the correct orientation of the plates' surface relative to certain lattice planes or crystal axes, can be determined in a few seconds measuring time with an accuracy of a few arcseconds using the so‐called “Omega Scan”. This method and its further development in the last time will be described in some detail.
