| 摘 要： | 利用Needle合成法与Conjugate graduate精炼法，并基于Thelen和Costich的理论选择初始膜系的材料和结构，设计了532，633和1 315 nm三波长消偏振平板型分光膜。结果表明，此膜系在(532±10), (633±10)和(1 315±10) nm范围内的偏振分离都非常小。对于532，633和1 315 nm 3个波长位置的消偏振要求，入射角的合理变化范围可以是45±2°。

| Abstract: | With the Needle thin film synthesis method and Conjugate graduate refinement method, all-dielectric three-wavelength non-polarizing parallel plate beam splitters are designed. The chosen of materials component and initial stack are based on Costich and Thelen’s theory. The results of design and analysis show that it maintains a very low polarization ratio in spectral range of (532±10), (633±10) and (1 315±10) nm. To the requirement for non-polarizing in 532, 633 and 1 315 nm, the reasonable angular field of design can be 45°±2°. |
