在NGC 6334 V双极星云的L-prime波段（3.8微米）观察到了异常高的偏振度（高达100%）。观测到的对称偏振模式表明，该星云是一个反射星云，由两个被中心遮蔽的星星照亮的叶组成。偏振的分布要求其中一个瓣由柠檬形腔组成，该腔主要在其表面散射光，而圆锥形腔模型适用于另一瓣。叶瓣的这种不对称性可能是由于该区域周围云物质的密度梯度造成的。参考文献17篇。
Exceptionally high degrees (up to about 100 percent) of polarization were observed in the L-prime band (3.8 microns) toward the NGC 6334 V bipolar nebula. The observed symmetric polarization pattern indicates that the nebula is a reflection nebula consisting of two lobes illuminated by a central obscured star. The distribution of polarization requires that one of the lobes consist of a lemon-shaped cavity which scatters light mainly at its surface, whereas a conical cavity model is appropriate for the other lobe. This asymmetry of the lobes is probably due to a density gradient in the ambient cloud material in this region. 17 refs.
