    • PURPOSE: A far-infrared camera lens unit with high definition is provided to have high definition and low angle of view as being manufactured easily by being formed with molding. CONSTITUTION: A far-infrared camera lens unit has a first lens(L11), a second lens(L21) and a third lens(L31) in sequence from an object side(OBJ) toward the direction of an image side(IMG). The first lens has a positive refractive index of meniscus type having a first convex plane(b1) whose plane facing with the object side is convex. Both sides of the first lens are formed to be spherical surfaces. The second lens has a negative refractive index and both sides of the second lens are spherical surfaces. The third lens has a positive refractive index of meniscus type having a second convex plane(b2) whose second lens is convex.
    • 目的:提供具有高清晰度的远红外相机透镜单元以通过成型而容易地制造具有高清晰度和低视角。 构成:远红外摄像机镜头单元从物体侧(OBJ)朝向图像侧方向(IMG)依次具有第一透镜(L11),第二透镜(L21)和第三透镜(L31)。 第一透镜具有弯月面型的正折射率,具有与物侧相对的面为凸面的第一凸面(b1)。 第一透镜的两侧形成为球面。 第二透镜具有负折射率,第二透镜的两侧为球面。 第三透镜具有弯月面型的正折射率,其具有第二透镜为凸面的第二凸面(b2)。

    • The present invention relates to a wide-angle lens for a far infrared camera. The wide-angle lens comprises a first lens which has a positive refractive index for an object as a convex meniscus lens; a second lens which is disposed at the rear side of the first lens and has a positive refractive index as a meniscus lens convex in the opposite direction of the first lens, wherein a third surface and a fourth surface are aspheric; and an infrared filter which is disposed at the rear side of the second lens and only transmits far-infrared rays among incident rays. A focal distance between the first lens and the second lens satisfies mathematical formula 1, f1 > f2 and 2
    • 本发明涉及一种用于远红外摄像机的广角镜头。 广角镜头包括对于作为凸凹凸透镜的物体具有正折射率的第一透镜; 第二透镜,其设置在第一透镜的后侧,并且具有作为在第一透镜的相反方向上凸起的弯月形透镜的正折射率,其中第三表面和第四表面是非球面的; 以及设置在第二透镜的后侧并且仅在入射光线之间传输远红外线的红外滤光器。 第一透镜和第二透镜之间的焦距满足数学式1,f1> f2和2
