Measurement of birefringence
 

We measure the birefringence caused by the residual stress in a sample piece. Typically the Birefringence is indicated as the retardation per 1cm in (Unit = nm / cm). And as high precision measurement, we can also show the direction of fast axis in addition to the stress direfringence.
