Measuring apparatus

Abstract

A measuring apparatus includes a light source configured to emit light in a mid-infrared region, the light including: first-wavelength light having a wave number of from 970 cm−1 or more to 1010 cm−1 or less; and second-wavelength light different from the first-wavelength light, the second-wavelength light having a wave number of from 950 cm−1 or more to 990 cm−1 or less; a photosensor configured to detect the light emitted from the light source and reflected by a measurement target; and an information processing device configured to: obtain a first absorbance of the first-wavelength light and a second absorbance of the second-wavelength light from an output of the photosensor; and determine a biomarker of the measurement target based on the first absorbance and the second absorbance.
