The Corner Cube will reflect all light rays towards their source. As each face contrib¬ utes to the total amount of deviation the angular deviation can only be a fraction of the total deviation.
The above parameters are only for the normal optics' reference basis. Concrete specifications will be different according to different materials and dimensions.
