果実熟度簡易判定のためのマイクロ分光器を用いた分光光度計

抄録

The development of a low-cost spectrophotometer module and its performance evaluation are described. This module is intended for simple determination of fruit ripeness and is based on the principle of absorbance spectrophotometry in visible light and near-infrared. The module was able to observe absorption maxima in the Soret and Q bands for samples expected to contain chlorophyll, confirming that chlorophyll was sufficiently detectable. In addition, it can be a key device for simple fruit ripeness determination because it is small and can be made at low cost.
