本文介绍了一种新型低成本的液芯光纤分光光度系统。该系统突破了目前对液体折射率必须大于１．４６的限制，降低到１．３４６。系统的灵敏度达到ｎｇ／ｍｌ，误差小于０．０１，操作简便。
This article describes a new low-cost liquid-core fiber spectrophotometer system. The system breaks the current limit of 1.46 for a liquid that must be greater than 1.46 refractive index. System sensitivity to ng / ml, the error is less than 0.01, easy to operate.
