    • An image pickup lens is provided to gain excellent aberration by using a second lens having power which is stronger than a first lens and a third lens, and to arrange the first, the second, and the third lenses successively. A first lens(10) has positive power. A second lens(20) has negative power. A third lens(30) has the positive power and a point of inflection on an upper surface. The first lens, the second lens, and the third lens are arranged successively from an objection direction, and the second lens has the power stronger than the power of the first and the third lenses. The point of inflection of the third lens amends spherical aberration, comatic aberration, and astigmatism.
    • 提供一种图像拾取透镜,以通过使用具有比第一透镜和第三透镜更强的光焦度的第二透镜来获得优异的像差,并且依次布置第一透镜,第二透镜和第三透镜。 第一透镜(10)具有正光焦度。 第二透镜(20)具有负功率。 第三透镜(30)在上表面具有正功率和拐点。 第一透镜,第二透镜和第三透镜从反射方向依次布置,并且第二透镜具有比第一透镜和第三透镜的光焦度更强的光焦度。 第三透镜的拐点改变球面像差,彗形像差和像散。

    • A micro image pickup optical system is provided to obtain a high image property by making an imaging surface flat as the curvature of the surface of a third lens facing an object gets smaller from an optical axis toward the periphery and the curvature of the surface of the third lens facing an image gets bigger from an optical axis toward the periphery. A micro image pickup optical system is composed of a first meniscus lens(L1) having the positive refractive force and convex toward an object, a second meniscus lens(L2) having the negative refractive force and convex toward an image, and a third lens(L3) having the positive refractive force. The curvature of a surface(5) of the third lens facing the object is gradually reduced from an optical axis toward the periphery and the curvature of a surface(6) of the third lens facing the image is gradually increased from an optical axis toward the periphery.
