Summary:To provide a technique for improving accuracy in a bubble measuring apparatus for measuring bubbles contained in a solid sample.SOLUTION: A bubble measuring apparatus 10 includes a light source for irradiating a solid sample 20 with excitation light, an objective lens 30 for irradiating a predetermined position of the solid sample 20 with the excitation light and condensing reflected light from the solid sample, a spectrometer for detecting the condensed light, and measures bubbles contained in the solid sample 20. The solid sample 20 has a refractive index of 1.3 to 1.6, and the objective lens 30 is configured as an immersion objective lens 30. When measuring bubbles 32, an optical path from the solid sample 20 to the immersion objective lens 30 is filled with a liquid 34 having the refractive index of 1.3 to 1.6.SELECTED DRAWING: Figure 2 【課題】 本発明は、固体試料の内部に含まれる気泡を測定する気泡測定装置における精度向上技術に関する。【解決手段】 固体試料20に励起光を照射する光源と、前記固体試料20の所定位置に励起光を照射するとともに該固体試料からの反射光を集光する対物レンズ30と、集光した光を検出する分光器を備え、固体試料20に含まれる気泡を測定する気泡測定装置10である。固体試料20は屈折率が1.3〜1.6であり、前記対物レンズ30は、液浸対物レンズ30として構成されている。気泡32の測定時において前記固体試料20から液浸対物レンズ30までの光路は、屈折率が1.3〜1.6の液体34で満たされていることを特徴とする。【選択図】 図2
