    • PURPOSE: To obtain a compact photographic lens having high resolution and composed of small number of lenses. CONSTITUTION: This photogrpahic lens is composed of an aperture disphragm which is arranged nearest to an object side, and a 1st lens group, a 2nd lens group and a 3rd lens group which are arranged in this order from the objeect side. The 1st lens group is composed of a 1st lens (a positive lens) having positive refractive power and a 2nd lens (a negative lens) constituted to be joined with or separated from the 1st lens and having negative refractive power in this order from the object side. The 2nd lens group is composed only of a 3rd lens being a positive lens, at least one refractive surface of which is made aspherical. The 3rd lens group is composed only of a 4th lens being a negative lens, at least one refractive surface of which is made aspherical.
    • 目的:获得具有高分辨率并由少量透镜组成的紧凑型摄影镜头。 构成:该照相胶片由最靠近物体侧的孔径组合物构成,第一透镜组,第二透镜组和第三透镜组按照该方向依次排列。 第一透镜组由具有正折光力的第一透镜(正透镜)和与第一透镜接合或分离并具有负折射光焦度的第二透镜(负透镜)构成,该物镜从物体 侧。 第二透镜组仅由作为正透镜的第三透镜构成,其至少一个折射表面被制成非球面。 第三透镜组仅由作为负透镜的第四透镜构成,其至少一个折射表面被制成非球面。

    • The present invention relates to a lens structure for a camera of a black box for a vehicle and, more specifically, to a lens structure of a black box for a vehicle to improve the performance of the black box for a vehicle by adjusting a distance between a plurality of lenses and the aperture of each lens. The lens structure includes a first convex lens (12) through which external light passes, a second convex lens (13) coupled to the first convex lens (12), a first concave lens (14) coupled to the second convex lens (13), and a compound lens (15a, 15b) coupled to the first concave lens (14). The external light passing through the first convex lens (12), the second convex lens (13), and the first concave lens (14) forms a real image on a sensor (32) via the compound lens (15a, 15b).
    • 本发明涉及一种用于车辆的黑匣子的相机的透镜结构,更具体地,涉及一种用于车辆的黑盒的透镜结构,以通过调节车辆的黑盒之间的距离来改善车辆的黑盒的性能 多个透镜和每个透镜的孔径。 透镜结构包括外部光通过的第一凸透镜(12),耦合到第一凸透镜(12)的第二凸透镜(13),耦合到第二凸透镜(13)的第一凹透镜(14) 以及耦合到第一凹透镜(14)的复合透镜(15a,15b)。 穿过第一凸透镜(12),第二凸透镜(13)和第一凹透镜(14)的外光经由复合透镜(15a,15b)在传感器(32)上形成实像。
