红外中空光纤是一种用于光谱气敏的光纤，其内表面有一层银膜和一层介质膜以提高反射率，通过优化介质材料和薄膜厚度，实现了从可见光到中红外波段的低损耗；低损耗的中空纤芯光纤不仅可以作为气体传感的吸收池，还可以作为红外光的传输介质。初步实验结果表明，中空纤维是实现光谱气敏小型化的一种很好的气室替代材料。
Infrared hollow fibers were developed for spectroscopic gas sensing.The hollow core fiber has a silver film and a dielectric film on its inner surface to enhance the reflection rate,and thus to low the transmission loss.The chemical silver mirror-reaction method and the liquid-phase coating technique were used to form the silver and the dielectric film.Low-loss properties were achieved from the visible to the mid-infrared wavelength regions by optimizing the dielectric material and the film thickness.The low-loss hollow core fiber can be used not only as the absorption cell for gas sensing but also as the transmission medium for infrared light.Primary experimental results show that the hollow fiber is a good alternative for gas cell for miniaturization in spectroscopic gas sensing.
