And if the prism is of sufficient dimension that Angle can be magnified.
如果这个棱镜有多个面，可以把角度也放大。

The mechanical devices has been designed and produced to the fixed laser, mirror, prism and cameras, with the position and Angle of the mirror and prism adjustable.
设计制作了能够固定激光器、反射镜、三棱镜和相机，且反射镜、三棱镜位置角度可调的机械装置。
