Abstract: In an apparatus for measuring an optical characteristic of a sample, one object of the present invention is to provide an apparatus capable of measuring hemispherical total reflectance, hemispherical total transmittance, and light distribution, and to achieve a reduction in measurement time and an improvement in precision of the quantitative analysis of hemispherical total reflectance (transmittance). In a double ellipsoidal optical system which is an optical system in which one focal points of two ellipsoidal mirrors are positioned as a common focal point, and three focal points are aligned in a straight line, the double ellipsoidal optical system is composed of a partial ellipsoidal mirror 2, such as a quarter ellipsoidal mirror, and a belt-shape ellipsoidal mirror 1. By disposing, on a position of a focal point of the partial ellipsoidal mirror, a hemispherical detection optical system having a hemispherical lens or a rotational parabolic mirror, light scattered by an object, reflected by the partial ellipsoidal mirror, and focused on the point is photographed by for example a CCD camera 6 via a hemispherical lens and a taper fiber 5 so as to measure an optical characteristic of the object.
