DESCRIPTION

The accidental birefringence apparatus permits the observation of birefringence due to the compression of glass. There is a series of right angled prisms which can be inserted in the apparatus where pressure can be applied by a screw activated by a handle. Then the image of a light source seen through the distorted prism is doubled.
