Quartz taper fiber, also known as variable core diameter fiber, is a kind of tapered fiber with linear core diameter and continuous length along the length direction. it is composed of tapered segment (long L1) and tail fiber (long L2). In the tapered region, the core diameter and outer diameter change gradually from large to small along the length direction, and the tail fiber is a cylindrical optical fiber segment that keeps the core diameter of the thin end unchanged along the length direction, and its length can be determined according to the actual needs. The variable core diameter optical fiber is different from the existing ordinary cylindrical optical fiber. It is a tapered optical fiber whose core diameter varies linearly along the length direction. As a new type of optical fiber, the input of large core diameter can improve the damage threshold and transmission efficiency; the output of tail fiber with small core diameter can converge the energy of light, increase the energy density, and improve the stability and flexibility of the system. It can be widely used in laser medicine, industrial processing, signal sensing, ammunition remote blasting, UV curing, laser diode coupling, data storage, image sensing and other fields. 2.Product specifications and models

3.Ordering instructions Fluorine-coated fiber can not be used in the transmission of high-power laser, but is generally made into beam transmission, which is used for the transmission of visible light and ultraviolet fluorescence. 八、Radiation-resistant quartz optical fiber
Because the skin layer of the quartz fiber is doped with fluorine, the radiation resistance of the quartz fiber is improved, and high-energy information transmission can be realized. The characteristics of this radiation-resistant quartz fiber are: the radiation-resistant quartz fiber can withstand the transient irradiation of γ-rays at a dose of 100 Gy / h, and there is no significant change in the transmission performance of the fiber at the dose for 20 minutes. This radiation-resistant quartz fiber is suitable for high-energy transmission or image transmission in an irradiated environment.
