Abstract
A spectral image sensor device comprises a first optical systemandincluding an objective lens, a luminous fluxes selecting memberfor allowing a part of the luminous fluxes to pass via the first optical system selectively, an optical memberwhere the luminous fluxes selecting member is disposed so as to be at focal position on an object side or approximately at focal position on an object side, and an interference membrane is formed, and wavelength range of the luminous fluxes for passing through the luminous fluxes selecting member is selected, depending on position of the luminous fluxes selecting member, a second optical systemfor guiding the luminous fluxes toward the optical member, and an image sensorfor receiving a light in wavelength range as selected by the optical member.
