様にしたことを特徴とするビーム整形用レンズ。 A rectangular parallelepiped having a first portion and a second portion, wherein the first portion refracts in a first direction perpendicular to the optical axis such that the refractive index decreases as the distance from the optical axis increases. The refractive index distribution is changed in the second portion so that the refractive index increases as the distance from the optical axis increases in the first direction, and the refractive index distribution is changed in the second portion in the first direction perpendicular to the optical axis. A beam shaping lens characterized by having a constant refractive index in a second direction perpendicular to .
