Light scattering light guide and applied optical apparatuses

A light scattering light guide comprising a polymer material produced by the process comprising the steps of:

• (a) providing first and second organic substances, the first organic substance being a monomer and the second organic substance being a polymer, a polymer of the fast organic substance having a different refractive index and a different compatibility than those of the second organic substance;
• (b) preparing a mixture by substantially completely dissolving the second organic substance in the first organic substance;
• and
• (c) allowing the first organic substance in the mixture to polymerize so that as polymerization proceeds, compatibility with the second organic substance decreases causing the second organic substance to coagulate,

A light scattering light guide comprising a polymer material produced by the process comprising the steps of:
