OPTICAL SYSTEM FOR MICROCHEMICAL ANALYTICAL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a high general purpose optical system suitable for a high- performance process for a microchemical analytical system. SOLUTION: The optical system for guiding a light from a plurality of parts to be detected (flow cells, capillaries or the like) existing in a micro-fluid chip to a sensor 19 comprises an optical switch 16 and an optical fiber 13 connected to the switch 16. The fiber 13 is opposed to the respective parts of the chip 11. The switch 16 selects a necessary optical path by a switching mechanism as needed.
