core glass rods

The fiber-optic preform is a kind of glass rod made by melting a variety of raw materials (such as quartz sand and lanthanum oxide, mixed by weighing according to the proportion) under the high temperature environment. Generally, the diameter of fiber-optic preform is from several millimeters to tens of millimeters. The optical fiber preform guarantees the raw material supply in image photo-conductive recognition and low-light-level night-vision fields. Further, it can be used in the research and production of other new materials, such as photonic crystal fibers, fiber image bundles, optical fiber sensors, antiveiling photoelectric glass, scintillation glass and special photoelectric glass.
