Our control plates are manufactured using highly stable Single Crystal Quartz.
The crystal is one of the very first materials in which optical rotation is studied. Its rotation value and variation with wavelength and temperature have been established to a high degree of accuracy.
At DigiPol Technologies, our plates are properly manufactured and mounted, providing a highly stable optical rotation value. They are the calibration standard of choice for optical rotation measurements all over the world.
We provide plates traceable to NIST/ PTB in a few rotation value ranges and accuracy grades, including:
- Single Quartz Plates
- Double Quartz Plates
- High Accuracy Series
- Economy Series
