Abstract
PURPOSE: To make correction of lateral aberrations easy by making the end face of a refractive index distribution lens spherical.
CONSTITUTION: Laser light or the like from a spot light source 201 focuses on a prallel plane transparent glass plate 301 through a refractire index distribution type lens 801 such as optical fiber or the like whose refractive index at the optical axis is n0 and refracive index distribution n is based on formula I. Here, r; the distance in the radial direction from the optical axis; α: the change in refractive index;. If the end faces 802, 802 of this lens 801 are made to spherical faces of the specified radii of curvature Rd, Rs, then the range of lateral aberration correction becomes larger than that of the case of correcting the lateral aberrations of the focusing luminous flux by selecting the secondary and tertiary coefficients developed from the formula I and determining the lens. In addition, the adjustment of the end face curvatures after the making of the lens may be readily accomplished and the correction of lateral aberrations becomes easy.
