YVO4


Yttrium alumate (YVO4) is an excellent birefringent crystal material, which is a negative uniaxial crystal. The crystal has good physical and mechanical properties, wide light transmission range, high transmittance, large birefringence coefficient and easy processing. YVO4 crystal can replace ice SPAR and crystal red stone in the field of optical fiber communication, is the key material in optical communication passive devices such as optical isolators, circulators, polarization splitters, polarizers.

Exploring Birefringent Crystals: Essential Insights for Photonic Applications


Birefringent crystals are remarkable materials characterized by their ability to refract light in two distinct paths. This property arises from their anisotropic structure, where the refractive index varies depending on the polarization and propagation direction of light.
