摘要： An image capturing lens and an image capturing apparatus are provided to improve optical performance of a single focus lens by arranging an aperture diaphragm between first and second lenses. An image capturing lens includes a first lens, an aperture diaphragm, a second lens, a third lens, and an IR(InfraRed) cut-off filter. A convex surface of the positive first lens is arranged toward an object. A convex surface of the negative second lens is arranged upward. A concave surface of the positive third lens is arranged upward. The lenses, the aperture diaphragm, and the IR cut-off filter are made of a resin material. Relations, 0.3

摘要： Provided is an image pickup lens (1)for a solid image pickup element, which is composed of three glass lenses. The image pickup lens (1) is constituted to have an array including, sequentially in a recited order from an object side, a first lens (L1) having a convex surface directed toward an object and having a positive refractive index, an aperture diaphragm (S), a second lens (L2) having a convex surface directed toward the object and having a negative refractive index, and a third lens (L3) having a concave surface directed toward the object and having a positive refractive index, and is also constituted to have all lens surfaces made aspherical. The image pickup lens satisfies the following conditional equations (A0) and (A1) so that it has a satisfactory optical performance and a compactness at a low cost for a solid image pickup element. Also provided is an image pickup device employing the image pickup lens. f/f2
摘要翻译：提供一种由三个玻璃透镜组成的用于实心图像拾取元件的图像拾取透镜（1）。图像拾取透镜（1）被构造成具有从物体侧依次按顺序包括具有朝向物体的凸表面并具有正折射率的第一透镜（L1）的阵列，孔径光阑（ S），具有朝向物体的凸表面并具有负折射率的第二透镜（L2）和具有朝向物体的正面折射率的凹面的第三透镜（L3），并且还构成使所有的镜片表面成为非球面。图像拾取透镜满足以下条件式（A0）和（A1），使得其对于固体摄像元件具有令人满意的光学性能和低成本的紧凑性。还提供了采用图像拾取透镜的图像拾取装置。 f / f2 <-0.9 ---（A0）和2 <| R21-R22 | / | R21 + R22 | 其中f：整个透镜系统的焦距，f2：第二透镜的焦距（L2），R21：物体侧的第二透镜（L2）的透镜表面的曲率半径，R22：图像侧第二透镜（L2）的透镜表面的曲率半径。
