Description

Adapter for connecting optical fiber and film Technical Field The utility model relates to fixation and connection of an optical fiber and a film, in particular to an adapter for connecting the optical fiber and the film. Background The ordered porous material refers to a series of materials which have uniformly sized pores and are arranged in a spatially ordered manner, and can be an inorganic material or an organic polymer material. The ordered porous material has wide application prospect in the fields of life, chemistry, information, environment, energy sources and the like, and provides a model carrier for researching basic problems such as interaction among substances, energy transfer, behavior of the substances under extreme conditions and the like. The colloidal crystal is an ordered porous nano-structure material, can also be used as a template for preparing other ordered porous nano-structures, and is an ordered porous material with wide application. The crystal structure of the material is highly ordered, and has obvious Bragg diffraction effect, which can be attributed to constructive interference of light waves with specific wavelengths, and the diffraction effect is widely applied to a plurality of fields. However, the normal interference effect of ordered porous materials has not been sufficiently appreciated, and only a few researchers have focused on this, in fact, interferometry based on the optical effect of ordered porous materials has higher sensitivity and reliability than diffraction measurement. Biosensing platforms based on single-layer planar thin film interferometry have been developed, such as the biological layer interferometry techniques (Biolayer Interferometry, BLI), however the smaller specific surface area of planar thin films limits their further application, and therefore it is necessary to introduce ordered porous materials into the optical interferometry techniques, widening the application scenarios of the techniques. The three components essential in the optical interferometry technology are a light source, an optical film and a spectrometer, wherein the three components are directly connected by commonly using Y-shaped optical fibers and are respectively used for generating light, generating optical interference signals, collecting and analyzing the optical signals, and finally, the digital signals generated by the spectrometer are input into a computer for analysis and processing. The interfaces between the light source and the optical fiber, the spectrometer and the optical fiber, and between the spectrometer and the computer have realized mass production and are widely circulated in the market, and the optical film lacks a stable connecting device between the optical fiber due to the changeable forms and materials.
