ABSTRACT:
A microchemical system according to which measurement can be carried out with high sensitivity. The microchemical system1has a two-wavelength multiplexing device in which gradient index rod lenses501and502are connected together at an end face of each thereof and a dielectric multi-layer film filter503is formed between these end faces. Exciting light and detecting light is multiplexed by the two-wavelength multiplexing device, and then the exciting light and the detecting light are guided to an optical fiber unit10through an optical fiber101with a single mode. The optical fiber unit10has built therein a gradient index rod lens102at a leading end thereof, and the exciting light and the detecting light are irradiated onto a sample from the gradient index rod lens102.
