<p>PURPOSE:To provide an image forming element with a small chrominance aberration and with no difficulty in the manufacture of a lens itself. CONSTITUTION:This element is constituted of a reflection pair lines 3 where a great number of the pairs of reflection surfaces where the image forming elements are placed so that whose vertical angle forms a valley with pi/2 (radian) are arranged on a plane in a direction perpendicular to a valley line to which the reflection surface intersect and two rows of convex lens arrays 1, 2 arranged in parallel at an equal distance from the reflection pair lines and arranged in the arrangement direction equal to the reflection pair lines in a period larger than the reflection pair lines. Further, the element is constituted so as to be constituted of a reflection means arranged and opposed to respective convex lens arrays 1, 2 and revising optical paths passing through respective convex lens arrays 1, 2.</p> |
