Abstract

As optical systems become more complex, the designer is often forced to utilize exotic state-of-the-art materials to help solve difficult engineering problems. Often, as in the example presented here, the result is a design with inherent manufacturing problems. The component is a light weight beryllium mirror used in a Forward Looking InfraRed (FLIR) system. (Figure 1). The thin section design and the use of beryllium as the substrate material caused manufacturing problems.
实现高纵横比铍镜面的低应力光学光洁度
随着光学系统变得越来越复杂,设计师经常被迫利用外来的最先进的材料来帮助解决困难的工程问题。通常,就像在这里展示的例子中一样,结果是一个带有固有制造问题的设计。该组件是用于前视红外(FLIR)系统的轻质铍反射镜。(图1)。薄截面设计和使用铍作为衬底材料导致了制造问题。
