Abstract

The invention relates to an energy transmission optical fiber, which comprises an optical fiber and a layer of low-refractive-index coating coated on the surface of the optical fiber. The energy transmission optical fiber is characterized in that low-refractive-index coating comprises the following components in percentage by weight: 10 to 25 percent of fatty group urethane acrylate, 3 to 10 percent of vinyl silicone oil, 8 to 15 percent of perfluoroalkylethyl acrylate, 3 to 10 percent of TMMPS, 40 to 65 percent of trifluoro ethyl methacrylate and 3 to 8 percent of 2-hydroxy-2-methyl-1-phenylacetone. The energy transmission optical fiber has the advantage of reducing the production cost of the energy transmission optical fiber.

Description

technical field [0001] The invention relates to an optical fiber, in particular to an energy transmission optical fiber. Background technique [0002] At present, the energy transmission optical fiber is to draw the low-hydroxyl high-purity silica preform to a certain diameter, and coat a layer of low-refractive index coating on the surface of the optical fiber, so that the optical fiber can reach a high numerical aperture, increase the acceptance angle of the fiber core, and achieve transmission. Energy, simplify the optical path system. This energy-transmitting optical fiber can provide convenient and efficient coupling operations, and can be used in industrial automation, medical treatment, laser and other fields. However, there is no corresponding low-refractive-index coating in China, and it needs to be imported from abroad. However, this kind of low-refractive-index optical fiber coating is very expensive, which makes the production cost of energy transmission optical...
