The patterns show that divergence of the emergingbeam increases with the dihedral angle offset up to completely separate to six beams;
通过衍射图可以看出出射光束的发散程度随着角度误差的增加而增加,直至完全分离成六束光束。

After emerging from the lamp reflector, the p-polarized light would pass through a half-wave retarder that would occupy half of the beam cross section.
