摘要： This specification discloses a projection device in which a plurality of element lens systems for projecting a part area of an object onto a predetermined part area on the image plane at erect one-to-one magnification are arranged parallel to one another in a plane perpendicular to the optical axis. Each element lens system is a telecentric system comprising three thin lenses of the same shape arranged in the direction of the optical axis, and an intermediate lens is provided at a position deviated from the intermediate point between the object side lens and the image plane side lens. A light absorbing member for extinguishing any light rays exceeding the effective lens diameter is provided between the lenses, and the light intensity distribution on the image plane of each element lens system is controlled substantially to Gauss distribution form by aperture eclipse and, even if there is any error in the arrangement interval, the exposure amount distribution in the arrangement direction superposed on the image plane is uniform.
