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.

Abstract: There is provided an inspection apparatus which illuminates at least part of a sample with diffused light from a diffused light source and inspects the sample based on light reflected from the sample. An illuminating chamber is defined by a wall member. The wall member has an inner wall surface for reflecting diffused light from the diffused light source, a sample-inserting opening formed through the wall member for inserting the at least part of the sample into the illuminating chamber therethrough, and a sample-observing opening formed through the wall member for permitting light reflected from the at least part of the sample to be emitted out of the illuminating chamber. The sample is observed by the use of an object-side telecentric optical system having a lens system for collecting parallel light from the light emitted from the sample-observing opening, and an aperture stop arranged at or in the vicinity of a back focal point of the lens system.

Abstract: Colorimeter includes an illumination light reception unit, an attached part, a detection unit, a recognition unit, a color measurement control unit, and an output unit. To the attached part, a mask member is attached to cover the illumination light reception unit. The detection unit detects parts disposed on the mask member. The recognition unit recognizes information on the kind of the mask member in accordance with a detection result by the detection unit. The color measurement control unit causes the recognition unit to recognize information on the kind of mask member in accordance with the detection result at a first timing, and on the kind of mask member in accordance with the detection result at a second timing. The output unit performs a predetermined output in response to a discordance between the information on the kind of mask member at the first timing and at the second timing.

The thermal transfer film has good dispersion of the light-to-heat conversion material when the dispersion evaluation value ΔOD is 0.1 or less, and the thermal transfer film has poor dispersion of the light-to-heat conversion material when the dispersion evaluation value ΔOD is greater than 0.1. ΔOD=|OD2−OD1|  Equation 1 OD1=−log(T2/T1)  Equation 2 OD2=−log(T3/T1)  Equation 3
