ABSTRACT:
An imaging optical instrument causes light emitted from a plurality of light sources arranged adjacent an object to image on recording surfaces of a photosensitive or thermosensitive material. The optical instrument includes a two-sided telecentric optical system having a first lens disposed adjacent an entrance end of a lens barrel, and a second lens disposed adjacent an exit end of the lens barrel, and an aperture stop disposed adjacent a meeting point of a rearward focus of the first lens and a forward focus of the second lens. The aperture stop has an aperture formed centrally thereof for allowing passage of beams that should contribute to image formation, and a refracting portion surrounding the aperture for refracting beams that should be intercepted and causing these beams to leave the lens barrel from the exit end thereof.
