By analyzing the limitations that achromatic gradient-index (GRIN) lens solutions in the radial and axial extremes place on lens thickness and surface curvature, a radial-axial hybrid GRIN theory is developed in order to overcome these restrictions and expose a larger solution space. With the achromatic hybrid GRIN theory, the trade-offs between thickness, curvature, and GRIN type can be directly studied in the context of size, weight, and power (SWaP) reduction. Finally, the achromatic solution space of a silicon-germanium-based material system is explored, and several designs are verified with ray tracing.
通过分析径向和轴向极端情况下消色差梯度折射率（GRIN）透镜解决方案对透镜厚度和表面曲率的限制，开发了一种径向-轴向混合GRIN理论，以克服这些限制并开拓更大的解决方案空间。利用消色差混合GRIN理论，可以在尺寸、重量和功率（SWaP）降低的背景下直接研究厚度、曲率和GRIN类型之间的权衡。最后，探索了基于硅锗材料系统的消色差解决方案空间，并通过光线追迹验证了几种设计。
