Quartz control plates are measuring standards, used as testing and adjusting kits for polarimeters. Thin quartz plates (0.4 to 1.6 mm thickness) are polished with highest precision vertically to the axis and plane parallelly. For reasons of mechanical stability, plates with a low angle of rotation (between -24 °Z and +24 °Z) are produced as double quartz plates (combination of a dextro and a laevorotatory plate).
For each SCHMIDT+HAENSCH quartz control plate a factory certificate is supplied, indicating the absolute angle of rotation in angular ° and °Z for the wavelength 546, 587, 589 and 882 nm. The angle of rotation of the quartz plate is directly correlated to its thickness and will be indicated at a temperature of 20 °C for the wavelength 589 nm.
