[Pg.565] WebRefractive index of Sapphire. Sapphire is a uniaxial crystal, and its optical axis is the c-axis 〈 0001 〉. Therefore, it has birefringence, and birefringence appears when light is incident from a direction at an angle to the optical axis. When light is incident parallel to the c-axis, the optical axis, the refractive index is limited to ...

Webcrystal 0.5 µ - 5 µ. • The refractive index of the crys-tal must be significantly greater than that of the sample or else internal reflectance will not oc-cur – the light will be transmitted rather than internally reflected in the crystal. Typically, ATR crystals have refractive index values be-tween 2.38 and 4.01 at 2000 cm-1. WebThis causes a spatially varying refractive index within the material that can be observed as beam distortions. This can result in permanent damage to the crystal. However, under some circumstances, if the effects are small the damage can be reversed by heating the crystal to 200°C for a couple of hours to allow all the charge carriers to re ...
