To provide an optical sample to be applied to highly accurate measurement using light.SOLUTION: An optical member set includes multiple optical members having a reception area with light transmissivity. In each one of the multiple optical members, an optical absorption spectrum of a light reception area has at least one of a first optical absorption peak 101 and a second optical absorption peak 102. A first peak wavelength λof the first optical absorption peak 101 is equal to or more than 590 nm and equal to or less than 800 nm. A second peak wavelength λof the second optical absorption peak 102 is over 800 nm and equal to or less than 1,150 nm.SELECTED DRAWING: Figure 1【課題】光を用いた高精度の測定に適用可能な光学試料を提供する。【解決手段】光学部材セットは、透光性の受光領域を有する光学部材を複数含む。複数の光学部材のそれぞれにおいて、受光領域の光吸収スペクトルは、第１の光吸収ピーク１０１および第２の光吸収ピーク１０２の少なくとも一方を有する。また、第１の光吸収ピーク１０１の第１のピーク波長λｐ１は、５９０ｎｍ以上８００ｎｍ以下であり、第２の光吸収ピーク１０２の第２のピーク波長λｐ２は、８００ｎｍ超過１１５０ｎｍ以下である。【選択図】図１
