The phase retardation expression of ordinary and the extraordinary light in birefringence crystal is discussed.The common used expression is expanded a suitable fitting expression and the relations between its coefficient and the birefringence index are obtained. The use of the fitting expression is given. It can be a principle for designing liquid crystal and the pretilt angle tester using the method of crystal rotation.
