Is mainly used as additive for special optical glass and fibre glass slice with high index of refraction for electronic microscope and energy-saving light.
主要用作特种光学玻璃和光学纤维，高折射电镜片和节能电光源的添加剂。

The bi-refraction based this energy overlap mechanism should be more interesting for electronic waves in which there exists only the longitudinal polarized mode.
