PROBLEM TO BE SOLVED: To suppress an influence which is applied to a measurement result by adhesion of a sample to a mask plate.SOLUTION: A space formed by an integrating sphere is defined by an internal face of the integrating sphere. The internal face comprises a diffuse reflector. An opening formed on the integrating sphere exposes the space to outside of the integrating sphere. A hole formed on a mask plate is defined by an inner peripheral face of the mask plate. The inner peripheral face comprises a diffuse reflector. The hole comprises, on a principal plane of the integrating sphere side of the mask plate and on a principal plane of a sample side, a hole end on the integrating sphere side and a hole end on the sample side, respectively. The mask can be switched between a state of being attached to the integrating sphere and a state of being detached from the integrating sphere. When the mask is attached to the integrating sphere, a whole body of the hole end on the integrating sphere side is overlapped to the opening. A spherical space is formed by the hole formed on the mask plate and the space. A spherical internal face is formed by the internal face and inner peripheral face. The spherical space is defined by the spherical internal face.SELECTED DRAWING: Figure 6 【課題】マスク板への試料の密着性が測定の結果に与える影響を抑制する。【解決手段】積分球に形成される空間は、積分球の内面により定義される。内面は、拡散反射面を有する。積分球に形成される開口は、空間を積分球の外部に露出させる。マスク板に形成される孔は、マスク板の内周面により定義される。内周面は、拡散反射面を有する。孔は、マスク板の積分球側の主面及び試料側の主面にそれぞれ積分球側の孔端及び試料側の孔端を有する。マスクは、積分球に取り付けられた状態と積分球から取り外された状態とを切り替え可能である。マスクが積分球に取り付けられた場合は、積分球側の孔端の全体が開口に重なる。空間及びマスク板に形成される孔により球状の空間が形成される。内面及び内周面により球面状の内面が形成される。球状の空間は、球面状の内面により定義される。【選択図】図６
