Spectroscopic analysis device, spectroscopic analysis method and program for spectroscopic analysis device

摘要

A stray light ratio computation unit computes the stray light ratio at a specified wavelength based on the quantity of light at the specified wavelength computed by light quantity computation unit in a state where there is no sample having absorption in the light path and the quantity of light at the specified wavelength computed by light quantity computation unit when the light is transmitted through a sample having absorption at the specified wavelength. Stray light quantity computation unit computes the quantity of stray light at each wavelength through computations using the stray light ratio at the specified wavelength and different unique values for each wavelength (for example, different coefficients for each wavelength, stored in coefficient storage unit).
