Method of calibrating spectral apparatus and method of producing calibrated spectral apparatus

摘要

Creating a model calibrating spectral apparatus having an optical system that converts light to be measured into a spectrum, and a light-receiving sensor including a plurality of sensors that outputs signals, the sensors include sensors that output signals indicating respective energy amounts of a plurality of wavelength components. The model shows where a linear function of an indicator indicating a mechanical error in the spectral apparatus, expresses deviation of an indicator indicating spectral sensitivity of the sensor from the indicator indicating the reference spectral sensitivity of the sensor. The method comprises: a) acquiring reference spectral sensitivity; b) acquiring an indicator indicating the reference spectral sensitivity of the sensor acquired at a); and c) creating the model where the linear function of the mechanical error indicator expresses deviation of the spectral sensitivity indicator from the indicator indicating the reference spectral sensitivity of the sensor, acquired at b).
