技术注意事项

摘要: 在本文中我们回顾了红外变焦镜头的最新进 展，这些镜头可满足对减小尺寸、重量和功率 (SWaP) 的挑战性要求，同时能够在恶劣的环境条件 下以及在机载和便携式系统等受限平台上，实现高 的成像性能。描述了为下一代红外热成像系统和应 用优化的高级折叠式光学镜头和轻量级连续变焦镜 头的设计考量和性能。

When it comes to long-range, multispectral optical systems, large mirrors play an integral role; there are tens of thousands of optical units containing large mirrors around the globe. With minimum diameters starting at 200 mm, the largest mirrors range from 8.2 m in diameter (single mirrors) to over 10 m (segmented). They take many shapes — spherical, aspheric, parabolic, or freeform — and are used for a wide spectrum of light, including visible, UV, and IR.

大尺寸光学反射镜对许多光学系统起关键作用，它广泛用于各种重要的光学系统中。加工高性能大尺寸光学反射镜，需要满足一系列严格要求，给光学制造商提出了很多挑战。
