The application field of ultra-small spectrometers is expanding with the development of the trillion sensor society and the use of big data. Therefore, we have previously proposed a single optical fiber miniature spectrometer equipped with a light source. This small spectrometer was a system for directly measuring the reflectance of an object. This time, we propose a system to directly observe the transmittance of the target solution.
