棱镜
角锥
任意入射角,反射光线总是平行于入射光线,用于目标确定及快速对准等。

CPG为角锥提供各种类型的镀膜,如BBAR、铝、银、金等,我们也为其独特的应用镀P/R膜。
直角棱镜
CPG提供高精度直角棱镜,通常用于激光和医疗应用,直角棱镜通常用于弯曲图像路径或在90°重新定向光。

五角棱镜
五角棱镜具有稳定的光线偏离,即无论光轴和光线如何变化,它始终保持90度,多应用于土木测量中。
标准的五角棱镜反射表面镀有铝或增强铝,有时是黑色油漆。
五角棱镜的另一个变体是在它的一个表面添加一个楔棱镜,然后五角棱镜将被用作分束器,CPG也为很多客户或终端用户提供了这种产品。

道威棱镜
道威棱镜用于像面的旋转,入射光线和出射光线平行,在干涉测量,天文学和模式识别等领域的应用。
通常道威棱镜的形状是从一个截断的直角棱镜。一束光进入棱镜的一个倾斜面,从最长(底部)面的内部经过全内反射,并从另一个倾斜面出来。通过棱镜的图像是翻转的,因为只有一个反射发生,图像是倒置的,但不是横向移位。
