Abstract

PURPOSE:To measure at a time a wide range of wavelengths, by setting a filter that has different properties according to the areas on a substrate in front of the light receiving surface of a 1-dimensional image pickup element. CONSTITUTION:The incident beam passed through an incident slit 1 is supplied to a 1-dimensional image pickup element 6 via a collimator mirror 2, a plane diffraction grating 3, a camera mirror 4 and a filter 5 respectively. The filter 5 is a BPF formed on a substrate and disposed on the light receiving suface of the element 6. Furthrmore the filter 5 has different transmission properties at the long and short wavelength sides of a spectrum image, and the transmission property differs according to the area so that the short wavelength side has a shorter transmission wavelength than the long wavelength side. Such filter is formed on a substrate to cut the undesired beams at each point on the surface of a spectrum image. Thus a wide range of wavelengths can be measured at a time.
