A spectrophotometer includes a light source, a spectrometer separating light from the light source, a beam splitter separating a light path of the light separated by the spectrometer into sample-side luminous flux and reference-side luminous flux, a sample-side detector detecting the sample-side luminous flux that has passed through a measurement sample and a reference-side detector detecting the reference-side luminous flux that has passed through a reference-side sample, a controller obtaining spectral intensity distribution of the sample-side luminous flux from the measurement sample and spectral intensity distribution of reference-side luminous flux from the reference sample, wherein the controller repeatedly performs measurement of a baseline a plurality of times at a wavelength changing speed at the time of actual measurement for measuring the measurement sample, thereby performing an averaging process of averaging accumulated values of a plurality of measurement values of the baseline.
A spectrophotometer comprising:
A method of spectrophotometric measurement that separates light from a light source at a specified wavelength changing speed, detects luminous flux that is transmitted through a measurement sample, which is transmitted through the measurement sample, for each wavelength, and obtains spectral intensity distribution of the luminous flux that is transmitted through the measurement sample based on a measurement sample signal of the luminous flux that is transmitted through the measurement sample that is detected, wherein the method
A program for performing a procedure of spectrophotometric measurement that separates light from a light source at a specified wavelength changing speed, detects luminous flux that is transmitted through a measurement sample, which is transmitted through the measurement sample, for each wavelength, and obtains spectral intensity distribution of the luminous flux that is transmitted through the measurement sample based on a measurement sample signal of the luminous flux that is transmitted through a measurement sample that is detected flux,
