WebRefractive Index – the crystal should have a higher index of refraction than the sample. The majority of organic samples have refractive indices in the area of 1.5. Refractive indices of standard ATR crystals span from 2.4 to 4.0 – which in most cases provides sufficient sample to crystal differentiation.

A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. The simplest type of birefringence is described as uniaxial, meaning that there is a single direction governing the optical anisotropy whereas all directions perpendicular to it (or at a given angle to it) are optically equivalent. Thus rotating the material around this axis does not change its optica… WebRutile is an oxide mineral composed of titanium dioxide (TiO 2), the most common natural form of TiO 2.Rarer polymorphs of TiO 2 are known, including anatase, akaogiite, and brookite..

Other materials may become birefringent under special circumstances.
WebIn singly refractive minerals, light slows downs, refracts, and reflects internally. In doubly refractive materials, this process differs. Light splits into two paths due to the mineral's atomic structure and its two crystal axes of different lengths. You can see the effects of double refraction very well by examining calcite. WebRefraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, …
WebNegative refraction is the electromagnetic phenomenon where light rays become refracted at an interface that is opposite to their more commonly observed positive refractive properties. Negative refraction can be obtained by using a metamaterial which has been designed to achieve a negative value for (electric) permittivity (ε) and (magnetic) …
