A quartz control plate is a standard quartz tube consisting of optical rotation characteristics of a uniaxial quartz crystal. It consists of a uniaxial quartz crystal with a parallel plane after precision optical processing, a metal housing, a positioning ring and other precision optical components. It is used to calibrate polarimeters and saccharimeters.
