The article gives a design of an NIR instrument with filter. The working theory of the instrument is: during wheel running a circle , ray from light source irradiates the sample after it through a certain filter of filter wheel, so ray would carry the absorption spectrum of sample . We can know components of the sample by analyzing the ray . Filter wheel is its light splitter.

本文给出了一个使用滤光片作为分光器件的近红外光谱仪的控制电路设计方案，其工作原理是：当滤光轮转动时，光源出射光经过滤光轮上的某一滤光片，再照射到样品上，经样品池出射的光携带有样品的吸收光谱信息，滤光轮转动一圈，可得到样品不同波长处的光谱信息，通过后期数据分析可得到样品的成分含量信息。
