Spectroscopic camera and correction value calculation method for spectroscopic camera

Abstract

A spectroscopic camera 1 includes a relay lens optical system 19 configured to image light from an object and generate a first intermediate image at a predetermined position P1, a wavelength variable spectral filter 14 configured to spectrally separate the light from the relay lens optical system 19, an image sensor 15 configured to detect the light from the wavelength variable spectral filter 14, and a processor 20 configured to correct a spectral sensitivity characteristic of the wavelength variable spectral filter 14, wherein the processor 20 is configured to correct the spectral sensitivity characteristic of the wavelength variable spectral filter 14 so that the spectral sensitivity characteristic at an arbitrary correction point of a spectral image detected by the image sensor 15 approaches a spectral sensitivity characteristic at the predetermined reference point of the spectral image or a predetermined spectral sensitivity characteristic reference value.
