| 摘 要： | 讨论了应用于投影显示系统的满足宽光谱范围、大的入射角、高的消光比的偏振分光镜的设计和制备。提出了一种偏振分光镜的新的设计方法 :采用多对迈克尼尔对组合来满足宽入射角范围的要求 ,采用多个中心波长不同的λ 4膜堆来满足宽光谱范围。设计的偏振分光镜在 42 0nm～ 6 70nm的波段范围内 ,在 41.34°～ 48.6 6°的入射角范围内 ,达到p偏振光的平均透过率大于 85 % ,p偏振光的平均透过率与s光的平均透过率之比大于 10 0 0。并给出了设计实例和样品的实测结果

| Abstract: | The application of polarizing beam splitter for projection display system was reviewed. A new method was described for the design of polarizing beam splitter to meet the requirement of wideband and wide incident angle acceptance. Multiple Macneille Pairs were used and multiple central wavelength for λ/4 layer stacks combination were adopted in the design. The experimental results illustrated that the method was practicable. |
