The birefringence of (Ca 0.28 Ba 0.72 ) 0.75 (Sr 0.60 Ba 0.40 )Nb 2 O 6 crystal is measured basing on polarization-extinction method and conoscopic interference method. Experimental results show that the birefringence in this crystal is up to 10 -5 , the natural birefringence in this crystal is (n o
