Liquid light guide is a light transmitting element of new structure, it consists of a liquid material as core and polymer materials as cladding, characterized by large core diameter, large numerical aperture, broad range and higher efficiency of transmission., especially in UV light, comparing with ordinary silica optical bundle, and particularly suits to the spectral transmission in the fields of medical treatment, ultraviolet curing, fluorescent detection, criminal investigation and scientific research., according the ingredient of core material, liquid light guide is divided by two series, one is 300 series that of the best efficient transmission is 300nm～600nm., another is 380 series that of the best efficient transmission is 300nm～800nm。
