birefringence
double refraction

Does this produce a birefringence effect in the crystals themselves?

These tubes introduce what is called form birefringence to the cell.

It is important to try and find multiple like minerals in order to get the best value of birefringence.

Another is birefringence, where a double image appears when looking through a crystal.

Discovered birefringence, but was unable to give a scientific explanation.

If you want to know more, you might look for information on the term "birefringence".

They demonstrate birefringence based on the polarisation plane of the light.

However, when they are under mechanical stress, birefringence results.

The technique relies on the use of high birefringence fibre.

It depends on the fact that optical activity is actually circular birefringence.

The method is based on the property of birefringence exhibited by certain transparent materials.

More recent researches also haven't found any evidence for this effect, see section Birefringence.

Another form of birefringence is observed in anisotropic elastic materials.

These birefringence colors are of the first order.

A low birefringence has been required along with a high refractive index for many applications.

The birefringence means the decomposition of light into two rays when passing through a mineral.

This was suggested by birefringence analyses of cell walls.

Each mineral, depending on the orientation, may not exhibit the maximum birefringence.

From the birefringence point of view, spherulites can be positive or negative.

The system employs the natural birefringence of the calcite.

I don't think this could be called birefringence.

Misalignment leads to birefringence and to a large phase shift across the long crystal.

If a ray in this direction suffers no birefringence, neither will all parallel rays.

The theory of Huygens was not accepted, by some, because longitudinal waves cannot show birefringence.

It also has the birefringence of 0.007.
