K9平凸柱面透镜
产品特性：
N-BK7(K9)平凸柱面镜能把一个发光点发的光变成一条线，通过两个平凸透镜彼此垂直或是相交方向放置，就能产生面光，总的焦距就是各焦距的和。
K9平凸柱面镜从可见到近红外（350-2000nm）具有的透过率。

N-BK7(K9)平凸柱面镜
K9平凸柱面镜能把一个发光点发的光变成一条线，通过两个平凸透镜彼此垂直或是相交方向放置，就能产生面光，总的焦距就是各焦距的和。
与球面透镜相比，柱面透镜的制造难度更高。我们会合理选择材料(纹理，气泡，杂质，均匀性)，注意影响散乱的因素(划伤，凹痕，光泽)，研磨。
N-BK7(K9)平凸柱面镜从可见到近红外（350-2000nm）具有很好的透过率。H-K9L(N-BK7)是制备光学元件常用的光学玻璃，当不需要紫外熔融石英的额外优点（在紫外波段具有很好的透过率和较低的热膨胀系数）时，一般都会选择H-K9L。
N-BK7(K9)平凸柱面镜只在一个方向聚焦而另一个方向没有聚焦功能，和平凸透镜的外形尺寸相似，但是只在一个剖面上类似球面镜。为了小化球差，当将准直光束会聚成一条线时，应将平行光入射到柱面镜的曲面上。
