LIGHT WAVEGUIDE INCLUDING A PARYLENE COATING LAYER HAVING A REFRACTIVE INDEX HIGHER THAN THE REFRACTIVE INDEX OF THE MATERIAL OF THE LIGHT WAVEGUIDE MAIN BODY

摘要

PURPOSE: A light waveguide including a parylene coating layer is provided to improve a light concentration property and linearity.;CONSTITUTION: A light waveguide including a parylene coating layer comprises an light waveguide main body (10) and a parylene coating layer (30) formed at the upper part of the light waveguide main body. The light waveguide main body comprises glass or poly methyl methacrylate resin having excellent light transmissivity. The parylene coating layer is formed at the upper surface of a light waveguide main body in the method of chemical vapor deposition. The refractive index of the parylene coating layer is 1.59 to 1.66, transparency is 90% or greater and a haze value is 0.5 or less.;COPYRIGHT KIPO 2013
