We investigated the design and fabrication of liquid crystal polymer phase retarder. The liquid crystal polymer was aligned with the inorganic dielectric layer by glancing angle deposition. The retardation was measured by the Soleil–Babinet compensator. The average retardation of liquid crystal polymer retarder was 71 nm with the layer thickness of 385 nm. And the retardation tolerance was 1.4 nm with the nine-point uniformity test. The average transmittance of the phase retarder was 93.2% between 400 and 1200 nm wavelength without antireflective coating on its front and rear surfaces. This study paves a new way to fabricate the larger aperture phase retarders.

我们研究了液晶聚合物相位延迟器的设计和制造。通过掠射角沉积使液晶聚合物与无机介电层对齐。延迟由 Soleil-Babinet 补偿器测量。液晶聚合物延迟器的平均延迟为71 nm，层厚为385 nm。九点均匀性测试的延迟容差为 1.4 nm。相位延迟器在 400 和 1200 nm 波长之间的平均透射率为 93.2%，其前后表面没有抗反射涂层。这项研究为制造更大孔径相位延迟器铺平了道路。
