We present the evaluation and comparison of four different polymers (VeroClear, ClearVue, LOCTITE 3820, and WaterShed) to produce macro transparent optical components using additive manufacturing. The refractive indices were measured at increasing temperatures. The Cauchy and Sellmeier coefficients were fitted subsequently. We used the measured and calculated parameters to determine the Abbe numbers of materials at increasing temperatures. Several different lenses of the mentioned polymers with varying orientations were printed and evaluated according to transmission, imaging quality, and temperature-dependent behavior. The results were used to build an illumination demonstrator to simulate the sunlight as it is created by a roof window.

增材制造透明光学元件不同材料的评价与比较

我们介绍了四种不同聚合物（VeroClear、ClearVue、LOCTITE 3820 和 WaterShed）的评估和比较，以使用增材制造生产宏观透明光学组件。在升高的温度下测量折射率。随后拟合了柯西和塞尔迈尔系数。我们使用测量和计算的参数来确定温度升高时材料的阿贝数。根据透射率、成像质量和温度相关行为，打印并评估了具有不同取向的上述聚合物的几种不同透镜。结果用于构建照明演示器，以模拟屋顶窗户产生的阳光。
