PURPOSE:To permit mass production of titled bodies and arrays having stable quality by using not a partly polymerized agar-like gel base material but a nearly completely polymerized network polymer as a base material for diffusing a monomer. CONSTITUTION:The monomer Ma forming the transparent network polymer Pa having a refractive index Na is nearly completely polymerized to form the bar- or fiber-shaped base material. This base material is held in the liquid monomer Mb which forms the polymer Pb having the refractive index Nb different from the refractive index Na or in an atmosphere contg. the gaseous, mist-like monomer Mb and thereafter, or while said monomer is held therein, the monomer is heated to diffuse the monomer Mb from the surface of the base material into the inside thereof and completely polymerize the same. The monomer is harder and is less likely to be deformed then the partially polymerized transparent gel base material and, therefore, said monomer is extremely easy to handle in the stage of production. Since this base material has high dimensional stability as well, the mass production of the homogeneous light transmission body made of the synthetic resin having excellent optical characteristics is permitted. |
