Abstract
PURPOSE:To uniform the characteristics of a device of the same kind by correcting variance in limited wavelength due to a lot of wavelength band limiting members. CONSTITUTION:Mirrors 5-7 which guide reflected light from an original 2 lighted by a fluorescent lamp 3 on a CCD 4, a long-wavelength band cutting filter 8 as a wavelength band limiting member which limits the wavelength band of transmitted luminous flux, and a lens 9 which forms an image of the luminous flux transmitted through the filter 8 on the photodetection surface of a CCD 4 are provided in the optical path between the fluorescent lamp 3 and CCD 4. This filter 8 is provided so that it can slants to the optical axis of the luminous flux, and the inclination of the filter 8 is adjusted to vary the wavelength limited by the filter 8, thereby correcting the variance in the limited wavelength due to a lot of filters 8. Consequently, the optical characteristics of the same kind of device are held uniform.
