Learn more about this accessory

Quartz control plates are used as measuring standards, to test and calibrate polarimeters.

The surface of the thin quartz plates are polished with highest precision. 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 levorotatory plate).

For each SCHMIDT + HAENSCH quartz control plate a factory certificate is supplied, indicating the absolute angle of rotation in degrees (°) and wavelength, i.e. 405, 546, 587, 589.3, 589.44, 633 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.
