ROD LENS ARRAY, OPTICAL DEVICE, IMAGE SENSOR, PRINTER, INSPECTION APPARATUS, BASE GLASS COMPOSITION FOR GRADIENT-INDEX ROD LENS, AND METHOD OF MANUFACTURING GRADIENT-INDEX ROD LENS
This rod lens array 10a comprises a plurality of refractive index distribution-type rod lenses 1b arranged such that optical axes thereof are parallel to each other, and forms an erecting equal magnification image. A refractive index distribution-type rod lens 1b has a refractive index distribution in a radial direction. The radius of the refractive index distribution-type rod lens 1b is represented by r0. The central refractive index, which is the central refractive index of the refractive index distribution-type rod lens 1b, is represented by no. The refractive index distribution constant of the refractive index distribution-type rod lens 1b is represented by vA. The refractive index at a distance r from the center of the refractive index distribution-type rod lens 1b is approximated as n(r) = n0 ? {1 - (A/2) ? r2}. The opening angle ? represented by sin-1 (n0 ? vA ? r0) is 3 to 6°. The imaging distance of the rod lens array 10a is 45 to 75 mm. The depth of field, in which the value of a modulation transfer function (MTF) at a spatial frequency of 6 lines/mm is 30% or more, is 1.5 to 3.0 mm.
