Claim Text:
1. A spectroscopic analysis device which separates light which has passed through a sample in an optical path into lights of different wavelengths by a spectroscope and receives the lights of different wavelengths with respective different light receiving elements to compute the quantity of light of each wavelength in a light quantity computation unit based on a signal from each light receiving element, said spectroscopic analysis device comprising: a stray light ratio computation unit which computes a stray light ratio at a specified wavelength based on a ratio of: a stray light quantity computation unit which computes the stray light quantity at each wavelength through computations based on a product of the stray light ratio at said specified wavelength, the quantity of light at said specified wavelength computed by said light quantity computation unit in the state where there is no sample having absorption in said optical path, and different unique values for each wavelength, the stray light quantity corresponding to a magnitude of stray light.
