WebMar 11, 2024 · Applications. Birefringence has several applications. It can be used to find defects in the manufacturing process, or identify weak spots in plastic structure manufactured via injection molding. It is also used extensively in optical communications to change linearly polarized light into circularly polarized one and vice versa. http://www.mt-berlin.com/frames_cryst/descriptions/birefringent.htm

WebMay 19, 2016 · Some transparent substances cause light to bend or refract in two different directions, causing light to divide into two rays. This is called double refraction or birefringence. When you look at something through a birefringent substance, you can see a double image. Iceland spar, a type of calcite crystal, is birefringent. WebPure Yttrium Vanadate (YVO 4) crystal is a positive uniaxial crystal with a wide transparency range in infrared, a large birefringence, and excellent mechanical properties. It has been extensively used in fabricating birefringent plates, polarizers, isolators, circulators, and beam displacers. On this page are birefringent YVO 4 plates or blocks.
