Talk:Optical isotropy

Removed from article
I have removed the following material from the main page:


 * According to the textbooks of Optics isotropy means that the dielectric tensor is reduced to a scalar. Accordingly, materials with cubic crystal symmetry should have the same optical properties as polycrystalline or polydomain materials with random orientation of the crystallites or domains. This is only correct, however, if the domains are small compared with wavelength, otherwise polydomain materials depolarize light despite of being optically isotropic.

since this is way too deep without context and explanation, which I am not competent to contribute. For the moment I have created a basic definition and leave it to someone more expert in this field to expand the article. Cje 12:36, 27 March 2006 (UTC)
