REFRACTIVE INDEX MEASURING OPTICAL DEVICE, ITS MANUFACTURING METHOD AND REFRACTIVE INDEX MEASURING METHOD USING THE REFRACTIVE INDEX MEASURING OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a refractive index measuring optical device having enhanced measurement accuracy, and which is reusable and easy to manufacture, and to produce its manufacturing method and a refractive index measuring method that uses the optical device.;SOLUTION: A cyclic structure part 104, having a large number of protruded parts 102 and the recessed parts 103 held between them, is formed on the surface of a substrate 101 comprising a material, having a predetermined refractive index and a film 201 comprising a material having a predetermined refractive index, is formed on the surface of the substrate 101, while gap parts 202 and 204 not filled with the film 201 are formed to the recessed parts 103. If a liquid sample is injected in the gap parts 202 and 204, the refractive index of the liquid sample can be measured with high accuracy.;COPYRIGHT: (C)2006,JPO&NCIPI
