    Abstract: PROBLEM TO BE SOLVED: To provide a device for measuring an optical characteristic of an object to be measured, which is capable of measuring hemisphere total reflectance, hemisphere total transmittance, and light distribution while achieving a reduction in measuring time, and improving accuracy in a quantitative analysis of hemisphere total reflectance and transmittance.SOLUTION: A bi-oval type optical system is an optical system that has three focuses on an axis by combining each of one of respective focuses of two ellipsoidal mirrors into a common focus. The bi-oval type optical system includes a partial spheroidal mirror 2, such as cut into a quarter, and a plate-like spheroidal mirror 1. A hemispherical detection optical system, including a hemispherical lens 4 or a rotational parabolic mirror, is provided at a focus position of the partial spheroidal mirror. As a result, a light beam, scattered by an object to be measured, is reflected from a mirror surface of the partial spheroidal mirror to be condensed at the focus. A CCD camera 6 photographs the condensed light beam through, for example, the hemispherical lens and a tapered optical fiber 5 to measure an optical characteristic of the object to be measured.
