Polarimeter of the M-Series are high resolution polarimeters with following features:
Checking/Calibration
As the interference filters, which are used in circle polarimeters, suffer from age- and environment depending alteration, it might be necessary to check the wavelength accuracy periodically and to readjust the wavelength in case it’s out of range. This can be done with sucrose solutions or quartz control plates since the optical properties of sucrose solution and quartz are almost identical. Sucrose solutions are not very stable and have to be renewed regularly. Checking a polarimeter by a quartz plate is 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.
