A light trap is movable within a light scattering cavity of the device for controlling specular reflections during measurements. The light trap may be rotatable around the sample under test inside the cavity so that specular reflections off the sample can be included or excluded from the measurement. The sample may also be placed at the outside against a measurement port, and a measurement instrument is moveable on a rotating arm within or outside of the cavity.

Abstract: A spectrometer 1A is provided with an integrating sphere 20 for observing measured light emitted from a sample S of a measurement target, and a Dewar vessel 50 which retains a medium R for regulating temperature of the sample S, so as to cover the sample S and a second container portion 50b of which is located so as to face the interior of the integrating sphere 20. The sample S can be easily regulated at a desired temperature with the use of the Dewar vessel 50 retaining the medium R so as to cover the sample S. As the second container portion 50b is located so as to face the interior of the integrating sphere 20, the temperature of the sample S is regulated by the medium R, while inhibiting an external ambience around the integrating sphere from affecting the sample S. Therefore, the sample S can be efficiently regulated at a desired temperature.

Abstract: A spectroscopic measurement apparatus 1A comprises an integrating sphere 20 in which a sample S is located, a spectroscopic analyzer 30 dispersing the light to be measured from the sample S and obtaining a wavelength spectrum, and a data analyzer 50. The analyzer 50 includes an object range setting section which sets a first object range corresponding to excitation light and a second object range corresponding to light emission from the sample S in a wavelength spectrum, and a sample information analyzing section which determines a luminescence quantum yield of the sample S, determines a measurement value Φ0 of the luminescence quantum yield from results of a reference measurement and a sample measurement, and determines, by using factors β, γ regarding stray light in the reference measurement, an analysis value Φ of the luminescence quantum yield with the effect of stray light reduced by Φ=βΦ0+γ. This realizes a spectroscopic measurement apparatus, a measurement method, and a measurement program which can reduce the effect of stray light generated in a spectrometer.
