  • BIOCHEMICAL MEASURING DEVICE
    Publication number: 20100215545
    Abstract: A fiber switching mechanism of a lighting system for passing a light through one of n optical fibers corresponding to n channels sequentially is provided midway in n optical fibers of the lighting system corresponding to n channels such that lights from n optical fibers of a receiving system can be commonly received by a single spectroscope. With the fiber switching mechanism of the lighting system, it is possible to obtain measuring data of reflection spectrum of n optical thin film sensor portions by the single spectroscope.
