什么是光学系统
照明行业中的光学系统是指用于收集、聚焦和操纵光线的组件集合。这些组件包括透镜、反射镜和其他光学元件。光学系统在决定光束质量和光收集效率方面起着至关重要的作用。
光学系统包括各种类型的透镜和反射镜,每种透镜和反射镜都有各自的特性和局限性。F/# 比率描述了光圈与焦点距离之间的关系,是决定集光效率的一个重要因素。值得注意的是,在下列情况下,以面积等于镜面面积的圆直径为基础的 F/# 比以对角线为基础的 F/# 更有意义 考虑到集光效率.

输出光束的质量和具体应用是决定收集光有效性的关键因素。低 F/# 镜头可能会收集更多的光通量,但也会导致镜头像差增加,从而产生不完美的光束。因此,即使收集到更多的光,输出光束也可能无法有效地重新聚焦。
为了解决透镜像差问题并提高输出光束的质量,我们采用了各种技术和组件。例如,Aspherabs™ 的设计旨在减少像差,而双透镜则用于减少 F/1 聚光镜中的像差。此外,聚光透镜材料的选择对以下方面也很重要 光谱透射率精选的紫外线级合成二氧化硅具有最佳的紫外线透过率。
