N-BK7 楔形棱镜

可用于光束偏转
0.5可选° - 15° 光束偏转
备有未镀膜或镀增透膜产品
另外也备有不规则形状棱镜对

楔形棱镜可用于单独偏转激光光束至一定的角度，或者将两个楔形棱镜组合在一起作为光束偏转应用。单个棱镜可将入射光束偏移一定的角度，如果用屈光度测量的话就是一个屈光度，相当于在1米的距离下偏移了1厘米.

两个楔形棱镜可用来作为变形棱镜使用（用来校正激光管输出的椭圆形光束），或者用来将光束在4θ范围内以各种角度偏折，θ是指单个棱镜偏折的光。这种光束整形是通过分别旋转两个楔形棱镜来实现的，典型用于成像中的光束扫描不同位置。

注意: 光束偏差以度数和屈光度表示。一个屈光度是在离棱镜 1米距离下 1 厘米的偏差。
