Birefringent  Wedges

Product Description: 

A birefringent wedge divides a light beam into two orthogonally polarized beams. The polarization with the larger refractive index is deviated by a larger angle. Figure 1 shows an YVO4 birefringent wedge splitting a light beam into two orthogonally polarized beams with polarization parallel with optical axis by a larger angle.

 

Birefringent wedges are widely used in fiber optics such as isolators, circulator as well as other applications. Precision Micro-Optics offers superior quality YVO4 and LiNbO3 Birefringent wedges.
