As the interference filters, which are used in circle polarimeters, suffer from age- and environment depending alteration, it might be necessary to check and eventually to readjust the wavelength precise periodically. This can be done with sucrose solutions or quartz control plates, a much more reliable method.

Quartz control plates are long-term stable examination standards for polarimeter. The sample room of SCHMIDT + HAENSCH polarimeter permits the vertical movement of quartz control plates as well as the free rotation (±360°) around their own axis. Only by a rotation it is possible to check if the plates are mounted without strain and permit an examination of the polarimeter according to processing regulations of international standards like ICUMSA and OIML.
