Previous Next Birefringent Crystals # 6H35.10
Description: These calcite crystals are a birefringent medium, so they split one light beam into two beams. There are different indices of refraction for different polarizations. In p polarization, n=1.4864 and in s polarization n=1.6584. Placed on text, images appears double. Purchased/Built: purchased Setup Time: none Quant. in Demo Room: 4 Demo References Freier and Anderson Om-6 Use a second calcite crystal to show the polarization of the ordinary and extraordinary rays.
