    • An imaging lens includes a first lens group that includes sequentially from an object side, a first lens formed of resin and having a positive refractive power and a second lens formed of resin and having a negative refractive power, the first lens and the second lens collectively forming a cemented lens having a positive refractive power. The imaging lens further includes a second lens group that includes a negative lens having a convex surface directed toward an image plane and a third lens group that includes a positive lens, where the first lens group, the second lens group, and the third lens groups are sequentially arranged from the object side.
    • 成像透镜包括从物体侧依次包括第一透镜,由树脂形成并具有正折光力的第一透镜和由树脂形成并具有负屈光力的第二透镜,第一透镜和第二透镜共同 形成具有正折光力的胶合透镜。 成像透镜还包括第二透镜组,其包括具有指向图像平面的凸面的负透镜和包括正透镜的第三透镜组,其中第一透镜组,第二透镜组和第三透镜组 从物体侧顺序排列。
