PROBLEM TO BE SOLVED: To provide an optical measuring device capable of accurately measuring the light transmittance and reflectance of various kinds of samples.SOLUTION: An optical measuring device 1 includes an integrating sphere 20 including a spherical wall surface 29 in which a first opening 21 and a second opening 22 are provided, a light source 11 emitting a luminous flux going from the first opening 21 of the integrating sphere 20 toward the second opening 22 of the integrating sphere 20 through the inside of the integrating sphere 20, and a detector 12 arranged in a part of the wall surface 29 of the integrating sphere 20 and detecting a light quantity and measures the optical characteristics of a sample arranged in the first opening 21 or the second opening 22. The position of the detector 12 in the wall surface 29 of the integrating sphere 20 can be moved. |
