Abstract
The invention discloses a composite optical fiber based on a fluorescence detection system, and a preparation method thereof, and relates to the technical field of composite optical fiber materials. The composite optical fiber comprises: a fiber core rod, wherein the material component of the fiber core rod comprises semiconductor selenium powder; and a fiber core layer, wherein the material of the fiber core layer comprises tetramethrin modified polymethyl methacrylate. The preparation method specifically comprises the following steps: preparing the fiber core rod by adopting a melting pouring method; preparing a composite optical fiber, namely grinding and polishing a modified polymethyl methacrylate bar according to a size requirement; then processing a cylindrical hole in the rod, selecting the fiber core rod with a proper size, and filling the modified polymethyl methacrylate rod tube with the fiber core rod to obtain a composite preform rod; and then carrying out vacuum consolidation at 170-180 DEG C for 1-1.5 h, placing on a standard drawing tower, and drawing to obtain the composite optical fiber. The prepared composite optical fiber is excellent in mechanical property, good in heat resistance and low in water absorption; and the optical transmittance is good, the loss is low, and the application range is widened.
Description
technical field [0001] The invention belongs to the technical field of composite optical fiber materials, and in particular relates to a composite optical fiber based on a fluorescence detection system and a preparation method thereof. Background technique [0002] Optical fiber is a light transmission tool achieved by the principle of total reflection. The invention of optical fiber has significantly changed the way of life of human beings. At present, optical fibers have been widely used in fields such as biomedicine, industrial detection and intelligent manufacturing. Although optical fibers have a very wide range of applications in different fields, they are very simple from the perspective of material composition, and most optical fibers in use today are made of silica glass. Although it is also prepared from other glasses or polymers, silica glass is still the main raw material for the production of optical fibers. With the development of society and the progress of...
