Abstract
A projection apparatus for forming an image of original on a photosensitive material opposed to the plane of the original. The projection apparatus has a projecting system composed of a plurality of projection optical system arrays. Each individual projection optical system is composed of a first and a second lens coaxially disposed and having a relatively large length as compared with its effective lens diameter respectively. The first lens is an exit side telecentric lens whereas the second one is an incident side telecentric lens. The first lens forms an intermediate image of a portion of the original on a plane between the first and second lenses and the second lens reforms the intermediate image on the photosensitive material.
