Abstract: A projecting device having an array, in a plane perpendicular to the optical axis, of plural element lens systems each axially provided with two bar lenses of an axial length larger than the effective diameter thereof, characterized by the presence of an intermediate ring positioned between two bar lenses for extracting the effective beam emerging from the first bar lens and entering the second bar lens and providing a determined light intensity distribution on the projection plane.

Abstract: This specification discloses a projection device in which bar lenses of plastic, each having a great length in the direction of its optical axis as compared with its effective diameter, of the lenses are arranged in the form of a predetermined array. The bar lenses are shielded from the outside atmosphere by a holding member capable of easily setting the lenses. Further, transparent plates, such as glass plates or the like, are provided at the incidence end and the emergence end to seal the holding member, so that there occurs no deterioration of the predetermined optical performance resulting from variations in the environmental humidity which would otherwise cause variations in the plastic material.
