棱镜通常由附接到棱镜的透射光栅组成，并且构成光谱天文观测的重要光学元件。在这里，我们提出了一种新型的棱镜，其中包括一个体积相位全息光栅，并评估其性能的详细使用严格耦合波分析（RCWA）。基于从评估中获得的知识，我们能够设计和制造具有良好性能的棱镜原型。
A grism typically consists of a transmission grating attached to a prism and constitutes an important optical element for spectroscopic astronomical observations. Here, we present a new type of grism that includes a volume phase holographic grating and evaluate its performance in detail using the rigorous coupled wave analysis (RCWA). Based on the knowledge gained from this evaluation we were able to design and fabricate a grism prototype with good performance.
