Birefringence is when a material is able to refract light in two slightly different directions depending upon the angle of the light coming in. Crystals if calcite can be shown to do this.

What is a birefringence?

A birefringence is a splitting of a ray of light into two parallel rays of perpendicular polarization by passage through an optically anistropic medium.


What do you mean by optical density?

optical density is the amount of light


Definition of photo-elastic constant?

Optical glass is usually free of strain, but when mechanical or thermal stress is exerted upon it, glass shows birefringence. Stress F (Pa), optical path difference (nm) and thickness of glass d (cm) have the following relationship: In this case, proportional constant is called the photoelastic constant. It is listed in this catalogue at a unit of (nm/cm/105 Pa). The photoelastic constant is the material constant that will change by glass type. By using it, optical path difference can be computed from given stress. Internal stress can also be computed from optical path difference.


What is birefringence?

Everyone who is interested in faceting is likely to have seen the double image that is visible through a crystal of calcite. Most know that this is due to a property called 'birefringence' and that highly birefringent materials are often prone to cleavage and hard to polish.
